Securing the Perimeter

Perimeter security involves safeguarding a company’s network limits from outside interference. This includes hackers, intruders, and other rogue agents. Enforcing strict perimeter security involves surveillance detection, analysing and understanding patterns, recognizing threats – perceived and real, and creating a worse-case action plan to deal with them effectively.

A network perimeter can operate as an entry point or as a barrier to the internet or internal network. Security is critical for the integrity of the perimeter, not least against cyberattacks.

Perimeter Protection

A perimeter defence can be bolstered by adopting a range of several safety features. These will become more important in cases where cloud-based applications are used and when data resides in cloud storage. Examples of security measures include:

Firewall

Network security controls to monitor inbound and outbound traffic choosing to allow or block where appropriate

Intrusion Prevention System (IPS)

Preemptive identification of possible security threats with rapid response

Intrusion Detection System (IDS)

Monitor network traffic and analysis of suspicious activity of security threats

Virtual Private Network (VPN)

Secure, protected and encrypted internet connection over a public network

Existing networks can incorporate and include these features to further establish the integrity and security of the network perimeter. This is especially important as new and sophisticated threats emerge and defence strategies need to be adjusted accordingly.
