IT security audit

Comprehensive assessment of the security of the organization’s IT systems and data through checking the applied security measures, procedures and policies.

The purpose of the audit is to analyze the level of IT security, review IT security procedures and catalogue network resources. This allows to identify gaps in the systems, detect potential threats and prepare an action plan in case of a crisis situation.

IT security audits are used to determine the exact state of security of a network infrastructure or servers, the indicated IT system and determining compliance with the company’s IT security policies and procedures for ICT resources. The scope of the audit may include a fragment of the infrastructure with the possibility of extending it by a larger area or it may be focused on a selected element after finding irregularities in the state of IT security. IT security audits are performed by specialized teams of engineers acting as separate units or being a part of Security Operations Center (SOC) team responsible for ensuring continuous monitoring of ICT security. The result of an IT security audit is a detailed report presenting the examined area together with the detected irregularities and their severity, significance.

Information systems and networks require constant monitoring and should be subject to periodic IT security checks. Technological capabilities are constantly changing, and with them ways to break through security systems.
