Yen sun to commence operation at China plants
Aaron Lee, Taipei; Joseph Tsai, DIGITIMES
Wednesday 20 February 2019
Taiwan-based cooling concede developer Yen solar know-how will perceive its flowers in Dongguan quickly enter pilot creation for certification by means of its motor vehicle seller client and start mass construction in April with optimum means to reach over one million gadgets a month. The web site may breathe particularly used to meet orders from China, while flowers in southern Taiwan should breathe serving consumers from Europe, the us and Japan, based on Robert Liu, universal manager of Yen solar's digital Cooling Division.
Yen sun registered consolidated revenues of NT$290 million (US$9.33 million) for January, rising 17.seventy five% on year. on account of fewer working hours as a result of the Lunar modern year vacation trips, the company expects the amount to glide on month in February, however to settle on up in March. Some market watchers predict Yen solar's first-quarter consolidated revenues to reach a modern quarterly checklist with contributions from cooling and residential appliance items.
Yen solar is planning to expand means at vegetation in southern Taiwan and has built modern flowers in Dongguan, China to fulfill claim from the car sector.
Liu brought up that carriers are turning to center of attention on designing cars with lighter weight and less vigor consumption and the approach is anticipated to set off a wave of claim for heat dissipation options. Yen sun's visibility of such orders has already reached the conclusion of 2019 and the enterprise is already starting to design automobiles with customers for the subsequent three years.
presently, Yen solar has 65% of its revenues contributed by means of its cooling concede products with the ease coming from home appliance items. Of the revenues from cooling solutions, 38% are from automobile cooling and others workstation cooling.
currently, the flowers in southern Taiwan are capable of invent 120,000 contraptions of cooling fanatics a month and the company is looking to raise the quantity to 300,000 contraptions before the finish of the primary half.

And it’s off to an excellent birth for the solar Flyer 2 and its Siemens electric motor. The electric powered plane (e-plane) effectively achieved its first contemplate at various flight with the brand modern electric motor.
Bye Aerospace has been industrious the past few years furiously working on this e-aircraft, so the executives engineers beget to breathe over the moon about the electric solar Flyer 2 completing its first respectable flight on February eight at the Centennial Airport, south of Denver, Colorado.
above all, Bye Aerospace is focusing its flight checking out on its propulsion equipment, envelope expansion, and techniques optimization. it is using a fifty seven lb Siemens SP70D electric motor, which has a max vigor of 89.5 kW (a hundred and twenty HP) and a incessant vigor atmosphere of as much as 70 kW (94 HP).
Bye Aerospace is setting up a few plane within the sun Flyer household — a 2-seat sun Flyer 2 and a four-seat sun Flyer 4, as they in the past said. The company wants to construct the first FAA-licensed, functional, all-electric powered airplanes to serve the flight practicing and common aviation markets.
Bye Aerospace competes with one more e-plane maker, Pipistrel, which has its Alpha Electro. dwell tuned for an interview with Pipistrel pros, as well as electric powered flight leaders at Bye Aerospace and Siemens.
The FAA gave the solar Flyer 2 a ways 23 certification closing year in 2018. Bye Aerospace will continue checking out of the solar Flyer 2 prototype through 2019.
related to this examine flight, in line with George E. Bye, CEO of Bye Aerospace: “The airplane performed exactly as planned. My due to the total Siemens crew for their participation as they enter this subsequent, essential flight check section of sun Flyer 2 with the Siemens electric propulsion device.”
The company also has 2 different projects, the Stratoairnet, a solar-electric powered Unmanned Aerial automobile (UAV) and the uncommunicative Falcon UAV developed by uncommunicative Falcon u.s.a.applied sciences which you can find privilege here.Siemens’ acute position in the electric Aviation business
Siemens and its electric motors play a astronomical role in the electric powered aviation world, a noble deal relish Bosch pushed alongside the electric powered bicycle (e-bike) world. Siemens has already verified 260 kW electric motors earlier than on European e-planes. The definitely respectable intelligence is that it’s establishing propulsion technology with a whopping 10MW of energy, for commercial electric plane for the aviation transport sector. to this point, Siemens electric motors beget set at the least two velocity facts — the primary aero tow via an electrical plane and a modern world climb checklist with an altitude of three,000 meters in 4 minutes and 22 seconds.
Dr. candid Anton, government vice chairman and Head of eAircraft, Siemens delivered:
“This successful contemplate at various flight is a supercilious second for the Siemens and Bye Aerospace teams and marks a milestone in bringing the age of electric powered flight to life. The Siemens electric powered propulsion materiel offers a clear, cost-effective and uncommunicative propulsion option to the flight training market devoid of compromising performance or safeguard.”electric Airplanes Are closer Than You think
The electric vehicle (EV) rEVolution has been significantly underway for the past decade, but generally focused on land-certain motors. The maritime and aviation industries are now working extra significantly on the electrification of vessels and plane, however in a unique approach from the automotive industry. but don’t breathe fooled just because you don’t yet perceive a Tesla plane — Bye Aerospace and a yoke of other electric flight pioneers are bringing electric powered urban air mobility near us.

One of the driving forces behind the shuffle to storage area networks (SANs) has been the increasing importance and size of enterprise databases. As databases grew, administrators found that the only passage to efficiently manage and expand database storage is to tap into the flexibility of SANs. However, with the expanded expend of databases on storage networks, storage administrators now must deal with modern performance, backup, restore and management issues-not to mention how to obtain along with the database administrators (DBAs). Here's what storage administrators should know about marrying a database to a SAN.Oracle's Storage Push In a mark that database vendors are increasingly conscious of how necessary the storage behind their databases is, Oracle recently announced that it is launching a storage initiative, which seeks to combine the company's various individual storage initiatives into a strategic push to focus on how Oracle runs on storage. Oracle's initiative includes programs to certify interoperability of hardware components within an Oracle environment.
According to Allen Hoke, technical director, system platforms division of Oracle, "This program focuses on storage technology at a towering flush vs. their former focus on specific areas such as backup or particular storage hardware or storage management technology." In addition, Hoke says, "In order to provide a noble customer experience, they are teaming with their key OS, server hardware and storage partners to provide a remote champion strategy, aligned between us and their partners."
At this time, Oracle's partners comprehend EMC, HP, Hitachi, Network Appliance, Legato, Sun, and Veritas.
A few years ago, not many database applications ran on anything but direct-attached storage (DAS). As databases grew, however, administrators looked for easier ways to deploy storage and began using network-attached storage (NAS) to more easily scale their databases. With the advent of SANs, administrators are now finding that storage networks can provide even better performance for the most demanding transaction-oriented, towering volume databases.
Today, database applications are starting to shuffle from DAS to SANs. The reasons: increased ease and quicken of backup, better scalability, as well as enhanced reliability and performance. For many applications, a SAN is the only option available that provides the required performance.
Harold Durnford, a storage administrator at Royal Bank Canada, Toronto, Canada, says, "We've had Oracle, Sybase, UDB, and Informix on a SAN for quite some time. The reason they looked at storage area networks was the challenge of sharing big storage subsystems." In addition, he says, "It wasn't just a distance limitation, but also actual estate. With SCSI, they found they quickly ran out of SCSI ports on their arrays before they ran out of storage. They used the SAN to address fan-out."
Marty Ward, vice president of product management at Veritas has also seen this, and says, "Database users are very focused on scaling up and scaling out, which you can't conclude with dedicated storage."
Bob Rogers, chief storage architect at BMC says, "Consistent flush of performance is driving people to storage area networks, as are better trait backup and recovery tools. Those are entire very strong motivators to shuffle to a SAN environment, which is why very big customers beget embraced SANs and set databases on them quite early."
Jim Booth, director of systems engineering at CreekPath, agrees, saying, "People are moving to SANs primarily to obtain the performance. You can certainly implement a database on either NAS or a SAN. However, if you're doing it on a SAN, you obtain consistent throughput. Though it might breathe harder to manage, a SAN provides better performance and availability."
SAN configurationsA typical SAN configured for a database application includes database servers clustered for reliability and attached to a central network. At a minimum, two divide database servers are clustered together for redundancy, with dual redundant Fibre Channel (FC) fabrics connected to redundant RAID controllers. In many cases, path failover software such as EMC's PowerPath or Veritas' Dynamic Multipathing (DMP) is used to ensure multiple paths to the storage array, in conjunction with high-availability storage arrays and cluster software.
Michael Leo, a database administrator at Minneapolis, MN-based Caribou Lake Software, a consulting difficult which helps companies manage their systems, works with a big medical devices manufacturer replacing legacy Alpha VMS systems with Solaris machines, connected to an EMC Symmetrix SAN. "Everything is striped and mirrored [1+0]. They are using the SAN for development, production online transaction processing [OLTP] and production reporting-a data warehouse of the production database used for reporting. Each database is in the 100GB to 200GB range. They beget two copies of the OLTP database-one is a replicated charged standby, " says Leo. The systems elude Computer Associates' Ingres database.
"To back up the database, they are using the SAN for disk-to-disk backups. They then expend Veritas' NetBackup and a divide backup LAN to backup the SAN. To manage the disk space on the Sun, they expend Veritas in combination with EMC's SAN management tools," says Leo.
Database performanceOptimizing database performance has traditionally been done by configuring how and where tables and logs are stored, as well as configuring disks and storage for database access patterns. Database data is broken down into two principal types of data: tables-the actual data which is stored in the database-and logs, which are logs of the transactions to a database. Transaction logs are captious for recovering a database if there's a failure and are also used for replicating databases. Many databases can also expend their own indigenous file systems to maximize performance, maintain control over tables and avoid potential performance penalties imposed by file system buffering. Aside from quick storage, CPU and memory, administrators beget paid a lot of attention to balancing quicken vs. redundancy of data.
Database and storage administrators beget carefully selected RAID configurations-for example, using RAID 0+1-both mirroring and striping-in order to gain the greatest read performance from their hardware without losing redundancy. While RAID 5 provides for redundancy at a relatively lower cost, most database vendors today recommend RAID 0+1 for tables as well as logs and only recommend RAID 5 for less performance-critical backup volumes. Caribou Lake's Leo says, "Performance is highly contingent upon how you configure the SAN. They beget seen very noble performance for databases with RAID 1+0 sort configurations. They beget also seen decent performance for RAID 5, unless the RAID 5 is in rebuild. If the RAID 5 is in rebuild, write performance is so bad, the system may as well breathe down."
To further optimize access times and data throughput, database administrators beget to also invent confident that tables and logs never partake the same spindles on a disk. John Eisenschmidt, a DBA at the American Association for the Advancement of Science, Washington, D.C., says for his final install of Oracle, "We made confident not to set the index tablespaces with the data tablespaces to help read performance, and set the archive logs and redo logs in different places to balance write operations." Eisenschmidt manages about 2.5TB on a SAN filesystem on Xiotech hardware, used for storing user files, though he still runs his databases on raw dedicated disk.
However, with the advent of SANs and virtualized storage, administrators no longer beget that flush of control of data placement. According to Bob Rogers, chief technology officer of BMC Software, "Most DBAs are absolutely convinced that file placement is an absolutely captious issue, however, most disks today are virtualized-and users don't beget a clue where things are physically located."
Luckily, the quicken and manageability of storage beget improved the situation, despite the loss in control. Rogers says, "Today, you can obtain a much more consistent flush of performance by going to very big arrays such as those from EMC, IBM, and HDS than you could going to direct-attach disk."
Enter virtualizationDespite virtualization's equable march into storage systems, most vendors and users mediate that some control is still needed to fully optimize database access. Oracle's Hoke says, "One of the astronomical detestable things that can betide with virtualization is that you can beget two tables related in your trade application, with a towering flush of traffic in unavoidable rows of those tables."One passage to Dramatically multiply Database Performance Question: "Have you near across some difficult numbers and performance figures for the expend of RAID (at any level) in the database environment?"Securing PDAs with sensitive data - or access to it - should breathe taken seriously. Basically, you necessity to apply the same rigor to PDA security that you would to any other enterprise-class device, with a pellucid security policy and a uniform suite of security software. esteem the following:Chris Poelker: Database application performance shouldn't only breathe looked at from an I/O standpoint, but first and foremost from a design perspective. For example, at one customer site, they were using SQL server in a three-tier Web application, where the Web pages were built dynamically from the database. The design used active server page scripts in the application tier to query the database for results and the results were then sent to the Web server to build the dynamic pages.By moving to SQL - stored procedures at the database level, and tuning the indexing methods - and a slight schema redesign-performance improved by over 800%, entire without even touching the back finish I/O. Never cast hardware at a poverty-stricken design as the revert on investment is never as noble as taking the time to rethink the original design.Here's the some things to conclude for noble I/O performance:1) expend a lot of spindles. If you shuffle to and contemplate at the specifications on the designs to achieve maximum database performance, you'll notice they expend hundreds of drives. By a lot of spindles, I don't import big RAID sets. You should concatenate many smaller RAID sets into a separate LUN either by using host software or LUN virtualization within the storage hardware, if it has that capability.2) expend low latency paths to storage. Fibre Channel uses a packet-based network, which allows for a full duplex backend. On a SCSI bus, only one thing can betide at a time. Using dual-pathed Fibre disks, you can beget a read command on one side and a write command on the other side of the disk being queued at the same time.3) Spread the I/O load as much as possible. expend many HBAs in the server that are load balancing your I/O across entire the paths. Tools relish Veritas' Volume Manager or Solstice Disk Suite can champion conclude this by creating a separate LUN from many spindles on each path. By using 2Gb paths and four HBAs, you can obtain nearby to 800MB/sec to the LUN.4) expend the proper RAID flush for the log and database. Best drill here is log files should breathe on RAID 0+1 (RAID 10) and databases on RAID5 (RAID 0+1 can breathe used on the database for better performance if your budget allows for it).Performance. Today's difficult drives can achieve a sustained throughput of between 30MB/s and 50MB/s and 120 to 140 IOPS (I/Os per second) per spindle. The performance depends on the drive electronics, onboard cache size, rotation quicken (15,000 RPM is better than 7,200 RPM of course) and maximum hunt latency. If you partition your RAID set into petite partitions, and locate your data on the outer cylinders, your performance will shuffle up substantially. Doing this reduces the hunt time for a particular partition. Now just add up the number of spindles to design out your maximum IOPS. design 1680 IOPS using 14 spindles on one HBA, or 3360 IOPS using 2 HBAs to 28 disks doing 64,000 sequential I/O(random I/O will breathe less). Changing the shroud size of the transfer will either multiply MB per second (throughput) or IOPS. Smaller blocks invent IOPS shuffle up, larger blocks invent throughput shuffle up.These numbers are for direct I/O, acceptation no cache in front of the drives. Adding cache can multiply performance dramatically. I beget seen 33,000 IOPS on a separate LUN during 100% cache hit. So, if you want the best I/O performance available, expend a solid-state disk.Christopher Poelker is a storage architect at Hitachi Data Systems. He answers readers' questions on "Ask the Expert" at SearchStorage.com.
According to Hoke, a noble database administrator will try to spread those tables across multiple devices, so he doesn't create hotspots, and also for availability. However, with virtualization, those two tables may breathe inadvertently placed on the same disk, because virtualization masks physical locations. "Virtualization is powerful for provisioning storage because it's easy to shuffle data and add disks. But with a database, because of performance issues, there are potential drawbacks," Hoke says.
CreekPath's Booth agrees: "File placement is still absolutely necessary with a SAN, although disks beget gotten faster. It still comes down to laying down data on a spinning disk, and not putting redo logs and indexes on the same physical drives. That's why it's necessary for tools to perceive entire the passage down to the spindle level, so that when they're laying down data it's not stepping on its own toes."
Marty Ward, director of product marketing at Veritas concurs, although he doesn't mediate administrators necessity to breathe directly concerned with where data is, "DBAs don't necessity to breathe considered about which spindle disk data lies on. They acquire supervision of that for them. Their analytic volumes allow them to shuffle data around on-the- flit to adjust hotspots, even while running." Other vendors are also announcing tools in this area.
Durnford sees things the same way. "Using JBOD, you're much more sensitive to placements [hotspots]. However, using storage arrays, they expend their technology to shuffle storage around while running to purge hotspots, so that the server doesn't really necessity to know the physical storage location," he says. Durnford uses built-in tools on his Hitachi, IBM, and EMC arrays to deal with hotspots on his volumes.
SAN issues"In the obsolete days of NFS [network file systems], due to necessity of availability capabilities for Oracle, their customers saw storage corruption," says Oracle's Hoke. Because of those issues, Oracle's validation program for network-attached storage arose out of concern about the nature of NFS," he says.
In a SAN, storage just looks relish a SCSI disk-reducing a number of the headaches that came with putting databases on network-attached storage, since the interface is identical to that of SCSI. Unlike NAS - with storage networks Oracle has left it to their storage partners to qualify HBAs - switches and front-end storage FC adapters. Hoke says that with a SAN, "We beget not identified anything needing validation."
However, it still takes some drudgery to obtain SANs performing privilege for databases. DBA Eisenschmidt - despite running a SAN for his applications and file systems -is skeptical of using SANs for his database storage. "Our SAN, relish many I've seen, is optimized for storage capacity and file serving. While Oracle uses Xiotech's Magnitude in their test labs, I was pretty unhappy with the transaction performance they were able to obtain out of it."
CreekPath's Booth says, "The biggest issue with databases on a SAN is maintaining consistent throughput and access on a database while running other application sharing the same SAN."
Caribou Lake's Leo agrees, saying, "SANs often rescue an enterprise money by sharing I/O capacity across departments. But sharing I/O resources between the user files of one department and the DBMS storage for another is awful. The database management system's I/O characteristics are completely different than the user data files, and cache coherency becomes an issue."
Royal Bank of Canada's Durnford has opted for divide storage networks to resolve some of these problems. He says, "For tape, we're looking at a divide tape SAN. The issue there is database traffic is very time-sensitive, where tape traffic is very backup-oriented. Though you might mediate it's time shifted, we've found there's overlap."
The other issue most DBAs mention is the complexity of managing storage networks, which are typically managed by divide storage infrastructure staff. "A lot of progress has been made in the final yoke years, but most system administrators want SANs that are easier to administrate. I want a more liable SAN whose caching I'm not fearful to turn on," Eisenshmidt says.
Leo says that when you set a database and storage together, "You realize that your SAN management team must drudgery closely with the DBMS team. They beget seen situations where SAN managers beget decided to change the SAN configuration because it seems wasteful or odd, not realizing how carefully tuned the setup was."
CreekPath's Booth also agrees, saying that while heedful tuning of how storage is configured can purge sharing issues, "Both DBAs and storage administrators necessity to breathe on the same page."
Despite the issues, some users beget had powerful success running SANs with their databases. John Brooks, vice president of storage engineering at Cleveland, OH-based National City Bank, runs an 18TB SAN, which is based on Brocade switches with IBM and Hitachi arrays. "We beget no issues with running on a SAN. Not even performance issues. It just seems to run," he says. Asked if he does anything special for databases, he says "For SQL and Oracle databases, they cast it on the SAN." Brooks attributes the necessity of issues to the relationship he has with his storage vendors. He says, "We conclude a lot of research, primarily in the interoperability area that might account for the necessity of issues. They drudgery very closely with their storage vendors to ensure certification and supportability of the environment, in case issues conclude arise."
Tools and techniquesBecause SANs' modern role as the primary storage for databases, there's now a necessity for improved tools and software to manage the combination of database applications and storage. "It would breathe nice if vendors could provide some sort of management appliance to track why a SAN partition was configured in a unavoidable way, thus preventing the loss of historically significant details when SAN management changes hands," says DBA Leo.
"If I could beget anything from a SAN to invent it better for a database, I'd question the vendors to write better drivers. Most of the drivers I've seen and worked with just command the OS the drive is gone when the SAN disconnects, instead of perhaps telling it to wait or trying to free the process," Eisenshmidt says.
Some vendors look to breathe listening and are increasingly focusing their efforts on getting their database to elude better on SANs, and their storage and infrastructure to better champion databases. Take, for example, Oracle's Hardware-Assisted Resilient Data (HARD) initiative (see "Oracle's storage push"). Oracle's Hoke explains, "We're working with hardware partners to verify that when Oracle data is transferred to a disk it can breathe read. This sounds simple, but with storage management and storage virtualization in storage networks, there are lots of cooks in the broth."
Part of Oracle's difficult initiative, EMC's Oracle Double Checksum appliance offers the capacity to verify Oracle data as it is written to arrays in microcode, ensuring that corrupted data is never written to disk. Competitor Hitachi Data Systems has also announced champion for the initiative, with a microcode-based verification of Oracle data in their Lightning 9900V product.
EMC also offers its Symmetrix Optimizer, which makes recommendations to administrators on where to rebalance data-a must for administrators looking for charged spindles. EMC has a nearby partnership with Oracle, including a dedicated engineering team at Oracle Redwood Shores. Chuck Hollis, EMC's vice president of products and markets says, "We beget 12 to 15 engineers inside Oracle, some dedicated to interoperability, and the ease to feature exploitation such as their Double Checksum product and integration between Oracle and their replication products."
Veritas also offers a host of products designed to drudgery with databases and SANs. The company's Database Edition products for Oracle9i, IBM DB2, and Microsoft Exchange, including mirroring, backup, replication and clustering features designed for those databases. According to Veritas' Ward, an upcoming release of the company's storage resource management product, "will map data entire the passage from a database environment in Oracle or Exchange, through files, entire the passage down to disks to present you which spindles and extents the data is written to."
BMC offers its PATROL for Storage Management product. BMC's Rogers says, "When you're working with Oracle or Sybase or Microsoft SQL server and even Exchange, they can expose that from a database perspective. For example; they can expose an Oracle instance that is on a Solaris box and attached to a SAN, and perceive where it is spread about. They can expose that through a topology manager-all of the connections, separate points of failure, and the passage the database is laid out on disk."
Despite complexities of managing databases running on storage networks, the benefits are clear. For big databases, there's really no better option that a SAN because of the flush of performance, consistency, redundancy, and scalability that a storage network provides. Storage and database administrators alike are finding that the only passage to champion their mission captious applications is to deploy their databases on a storage network. With so much at stake, storage and database vendors will continue to drudgery more in tandem to invent their products drudgery better together (see "Vendor independence: Are the trade-offs worth it?").
This article is the second in a chain that discusses a policy of security incident responses. The article describes the policy best practices and execution features — evaluation, containment, and eradication of and recovery from a security incident — for responding to a customer's incident within the policy scope.Like this article?

There beget been several large-scale worm attacks on the Internet since 1988 and highly visible and coordinated denial-of-service attacks in the final few years causing billions of dollars in damage. These attacks bespeak that responding to such incidents is increasingly more complicated and requires technical knowledge, communication, and coordination among the staff responding to an incident, along with an adherence to applicable standards and policies.
A security incident response involves several aspects of preventive, detective, and recovery measures. A preventive measure primarily involves risk control that mitigates the effects or deters the happening of an undesirable event. Examples of preventive measures are passwords, keycards, badges, contingency plans, policies, firewalls, and encryption. A detective measure identifies the happening of an undesirable event. Examples of detective measures are visitor logs, audit trails, motion sensors, closed-circuit TV, and security reviews. Detective measures also provide a means for reporting the happening of events. A recovery measure is a risk control that will, in a traditional sense, comprehend control policies, processes, or mechanisms that restore the integrity, availability, and confidentiality of information assets to their expected state. Examples of recovery measures are failing tolerance, backup, and catastrophe recovery plans.
Since the late eighties and early nineties, a substantial amount of information has been published on the topic of security incident response from the following organizations:
Australian Computer Emergency Response Team (AusCERT), http://www.auscert.org.au/
Brazil's Centro de Atendimento a Incidents de Segurança (CAIS), http://www.rnp.br/lang/cais_en/
Carnegie Mellon University's Software Engineering Institute's Computer Emergency Response Team/Coordination center (CERT/CC), which was initiated by the Defense Advanced Research Projects Agency (DARPA), http://www.cert.org
European Institute for Computer Antivirus Research, http://www.eicar.org/
German Computer Emergency Response Team (DFN-CERT), http://www.cert.dfn.de/
Internet Engineering task obligate (IETF) in the form of RFCs, http://www.ietf.org/rfc.html
Purdue University's Computer Incident Advisory Capability (CIAC), which is funded by the Department of Energy, http://www.ciac.org/ciac
SysAdmin, Audit, Network, and Security, http://www.sans.org
U.S.'s National Institute of Standards and Technology (NIST), http://www.nist.gov
In 1990, NIST, in conjunction with CERT/CC, CIAC, NASA, and other agency response teams, organized a cooperative activity known as the Forum of Incident Response and Security Teams (FIRST) at: http://www.first.org
This coalition brings together a variety of computer incident response teams from governments, commercial organizations, and academic organizations. FIRST fosters cooperation and coordination in incident prevention, prompts rapid reaction to incidents, and promotes information sharing and learning among the members of its community.
": Executing a Policy" is the second of a chain of articles that discuss a security incident response policy and execution. These articles are not intended to comprehend entire of the material from the above efforts. They are intended to capture the salient points of the security incident response process and to present them in the context of a trade entity that serves its constituents (that is, its customers).
The first article, "Responding to a Customer's Security Incidents—Part 1: Establishing Teams and a Policy," contains definitions of security incidents, security incident response, teams that typically are involved in an incident response, the pros and cons of the teams, and the scope and goals of the security incident response policy. In addition, it describes policy essentials for the notification aspect of a security incident.
This second article describes the best practices and execution of key policy features of responding to a customer's incident within the policy scope described in the first article. These features mainly comprehend evaluation, containment, and eradication of and recovery from a security incident. Subsequent articles will focus on incident follow-up, with a special accent on forensics, risk analysis, catastrophe recovery, and government and legal recourses, as well as proactive teamwork. The primary audience consists of computer security managers, security policy developers, system administrators, and other related staff, liable for the creation or operation of a computer security incident response policy and service.
