Security Reviews

In a security review, we focus on the conceptual aspects of a system, component, configuration or code. The experience of our security analysts allows us to identify critical security aspects and provide expertise for proper implementation. This offers you a security foundation or a second opinion on which you can build further - even before the go-live.

 

 

Concept Review

When developing concepts, all business requirements must be met simultaneously, often at the cost of security. We analyze your concepts, identify potential vulnerabilities and provide recommendations to improve security and implement best practices.

 

Firewall Rules and Zone Concept Review

Firewalls are among the most important and critical network components. In a firewall review, we assess whether your firewall configuration fits your general zone concept, whether they support the segregation of your networks effectively and whether your rules are correctly implemented to protect your systems following the least privilege principle.

 

Source Code Review

A single forgotten character or a single statement in the wrong place can make the difference whether your code is secure or not. While we do not offer full automated source code scanning, our analysts can assess critical components or specific security-relevant functions manually and in-depth. This allows us to challenge the code for logical flaws, which an automated tool cannot perform.

 

Configuration Review

Cloud infrastructure (such as Microsoft Azure, Amazon Web Services and Google Cloud Platform), proxies, web application firewalls, spam filters and any other security component can be configured in various ways. The services are very complex to configure and thus, they may end up with default or insecure settings. In order to gain the assurance that services are secure and equipped with the industries' best practices, we review your configurations and provide suggestions for improvement.

 

Hardening Check

Every single client and server in your network can be a target for hackers. We verify your Windows or Linux builds for vulnerabilities and best practices so that you get a solid and secure base image.

Hardening checks usually cover:

  • BIOS and disk encryption, physical security
  • Security policy and settings (GPOs)
  • Users, groups and permissions
  • Network and firewall settings
  • Active Directory specifics, single sign-on
  • Software & Services (Macro, AV, EPP, EDR, VPN, etc.)
  • Software restrictions (AppLocker, SELinux)
  • Data exfiltration measures (DLP)
  • CIS controls benchmarking
