During the last ten years or so,computer security has exploded as a field,both in terms of the complexity and breadth of the field,and the opportunities available for IT professionals focused security.Safety is an integral part of all IT,network management, to web,application and database development.But even with the utmost attention to safety,there is still much to do in the area,and opportunities for IT professionals in mind safety is not likely to diminish in the foreseeable future.
For those who already look to the field of IT security,or to improve your career,there are a number of certifications and training opportunities for those wishing to learn about IT-security and show that knowledge of the available current and potential entrepreneurs.However,many IT security certifications requires a higher level of knowledge,experience and commitment that might be beyond the reach of many new IT professionals.
A good certification to demonstrate basic knowledge of security is the CompTIA Security +certification.Unlike other certifications,such as CISSPor theCISM the Security+ has no experience or prerequisites required,although CompTIA not recommend that candidates have at least two years of experience with network security in general and in particular.Also suggest that CompTIA Security+ candidates to obtain the CompTIA Network +certification,but not required.
Although the Security + certification is an entry-level than others,a valuable certification remains in their own right.Indeed,the Security + certification is a must for the Department of Defense United States,and is accredited by both the American National Standard Institute (ANSI) and the International Organization for Standardization (ISO).Another advantage of the Security+ is that it focus regardless of the vendor,instead choosing to safety issues and technologies in general,without their focus on any provider and approach.
Topics Covered by the Security+ Examination
The Security+ certification is basically a generalist means that knowledge of the candidates evaluated in a number of areas of knowledge,as opposed to a focus on the IT sector.So instead maintain a focus on application security only,for example,questions about the Security+ cover a wider range of issues, in line with the defined by CompTIA.
- Network Security (21%)
- Compliance and operational security (18%)
- Threats and vulnerabilities (21%)
- Application, Data, and Host Security (16%)
- Access control and identity management (13%)
- Cryptography (11%)
The exam provides questions from all of the domains above,although it is somewhat weighted to give more emphasis on some areas.For example,you can expect more questions on network security as opposed to cryptography,for example.That said,you shouldn’t necessarily focus your studying on any one area,especially if it leads you to exclude any of the others.A good, broad knowledge of all the domains listed above remains the best way to be prepared for the test.
There is only one exam required to earn the Security+ certification. That exam (exam SY0-301) is comprised of 100 questions, and is provided over a 90-minute period. The grading scale is from 100 to 900, with a passing score of 750, or roughly 83% (although that’s just an estimate, because the scale changes somewhat over time).
In addition to the Security+, CompTIA offers a more advanced certification, theCompTIA Advanced Security Practitioner (CASP), providing a progressive certification path for those who want to continue their security career and studies. Like the Security+, the CASP covers security knowledge across a number of knowledge domains, but the depth and complexity of the questions asked on the CASP exam exceed those of the Security+.
CompTIA also offers numerous certifications in other areas of IT as well, including networking, project management and systems administration. And, if security is your chosen field, you might consider other certifications such as the CISSP, CEH, or a vendor-based certification such as the Cisco CCNA Security orCheck Point Certified Security Administrator (CCSA), to extend and deepen your knowledge of security.
