About perimeter security

Perimeter security is the information security discipline tasked with ensuring the company network is properly secured at the point it meets the internet. Imagine a high fence or wall the surrounds the perimeter of the network that has been designed to protect the information stored inside from malicious attacks and other catastrophic events.

Cybersecurity framework

1 – Identify – The ‘identify’ phase covers the information security governance, business processes, asset management, risk management and allows the company to assess its cyber risk prior to an attack in order to allow planning for all phases to take place.  This phase should always be revisited after an attack has occurred as it serves to prevent another attack of the same kind.

2 – Protect – The ‘protect’ phase is designed to actively prevent an attack from being successful. This stage consists of a GDPR “Technical Measures” requirement and may also contain “Organisational Measures” designed to prevent a successful attack.  The measures are a direct result of your information risk assessment created under the “Identify” phase.

3 – Detect – The ‘detect’ phase provides methods to detect a successful attack.  A company cannot assume an attacker will always be thwarted and the “Detect” phase ensures that should any of the protective measures fail – the company can detect and respond (Phase 4) to a breach at the earliest opportunity.

4 – Respond – The ‘respond’ phase details the company’s response to a successful attack – one which may have been detected by the measures in the “Detect phase” or by other means – such as a third party informing the company.  The respond phase is considered critical in organisational cybersecurity planning as it defines the actions needed to stop the attack and move into the recovery phase.

5 – Recover – Once the cyber-attack has been stopped and prevented from causing further damage, recovery work must be undertaken to restore services to business as usual.  The recovery phase will also include feedback into the “identify” phase to assess how to prevent a similar attack from being successful in future.
