How Network Security can help you be safe?

Knowing about Network Security can definitely help you in a technical job interview. So here's all you need to know about network security.

Network security starts from authenticating any user. Once authenticated, firewall enforces access policies such as what services are allowed to be accessed by the network users. Though effective to prevent unauthorized access, this component fails to check potentially harmful contents such as computer worms being transmitted over the network. An intrusion prevention system (IPS) helps detect and prevent such malware. IPS also monitors for suspicious network traffic for contents, volume and anomalies to protect the network from attacks such as denial of service. Communication between two hosts using the network could be encrypted to maintain privacy. Individual events occurring on the network could be tracked for audit purposes and for a later high level analysis.

Some of the steps that you need to take to project your system / network :

• Use virus protection software.
• Use a firewall.
• Don’t open unknown email attachments.
• Don’t run programs of unknown origin.
• Disable hidden filename extensions.
• Keep all applications (including your operating system) patched.
• Turn off your computer or disconnect from the network when not in use.
• Disable Java, Java Script, and ActiveX if possible.
• Disable scripting features in email programs.
• Make regular backups of critical data.
• Make a boot disk in case your computer is damaged or compromised.
