Perimeter security: Relying on a single layer of security for your IT systems is a problem that can have serious consequences. It’s important to understand the risks associated with relying on one system, and how it can be used by attackers to gain access to your valuable information and data.
Defence in Depth (DiD) is a cybersecurity strategy that uses multiple layers of security to protect a business’s critical assets and IT systems. Moving to this layered approach is effective as it secures all attack surfaces. If a malicious actor gets through one layer of defence with a novel attack method, they are likely to be stopped by a further layer of defence.
Following on from our first layer ‘Email and Web Security‘ – the second layer of defence is perimeter security. This layer includes technologies such as Next Generation Firewalls, Security Information. It also includes Event Monitoring and risk management solutions.
Next Generation Firewalls
Next Generation Firewalls (NGFW) are the latest generation of firewall technology that provide features beyond older firewalls. For example, a NGFW includes additional features such as intrusion prevention. In addition to, application awareness and control, threat intelligence sources and the ability to address evolving security threats.
An NGFW can block advanced malware, as well as provide a greater view of the network. This can make it easier to defend against threats.
Security and Event Management
Security and Event Management (SIEM) provides businesses with next-generation detection, investigation and response and show the threats. The detection and investigation components use behaviour analytics. AI and threat intelligence technologies are used to find any suspicious activities. A SIEM solution will respond to these incidents with built-in orchestration.
This makes it easier for businesses to manage the massive amounts of security data that’s being created at any point. This solution can also prioritise the alerts and potential actions.
Risk Management
Risk Management is the process of identifying, assessing, managing and fixing problems across a business. Most vulnerability management solutions enable asset visibility and provide predictions and prioritise the most critical risks on each asset, with things to do to mitigate the associated risk.
Vulnerability management makes it possible to defend against all known threats However, this process needs to be constantly managed. With these technologies, many attacks will be stopped in their tracks before they get anywhere close to a business’s data.
