Network Security

How to plan and implement secure networks, detect attacks and test security policies

• 4 days • £2860/$3640 • world-wide


You will learn:

    • Determine the risk to your network
    • Develop and implement a security policy
    • Audit your network's security
    • Use modern network security techniques, such as X.509, IPSec, SSL, TLS etc
    • Use ethical hacking to identify security weaknesses.
    • Harden your network services and applications
    • Keep up to date with security issues

     


Course Benefits

The growth of the Internet and the wide-spread use of computer networks have brought great benefits to businesses. At the same time they have opened up business systems to remote hacking from employees through to anonymous crackers at the other side of the world.

The related growth in network applications has increased the complexity and consequently the vulnerability of networked systems.

Whilst techniques to secure network systems exist they are many and complex. This course gives the attendee a good understanding of network security risks and the appropriate techniques that can be used to reduce and control those risks.

 


Who should attend?

This course is ideal technical staff and managers involved in network management. It is helpful if attendees have a basic understanding of networking principles but background information is supplied throughout the course.
