Description: Access security refers to the measures implemented to protect access to networks and computer systems, ensuring that only authorized users can access specific resources. This concept encompasses a variety of techniques and technologies designed to prevent unauthorized access, protect sensitive data, and maintain information integrity. The main features of access security include authentication, which verifies the user’s identity; authorization, which determines access permissions; and auditing, which records and monitors access activities. The relevance of access security lies in the increasing reliance of organizations on digital technology and the need to protect critical information from cyber threats. In an environment where cyberattacks are becoming more sophisticated, implementing access security measures becomes an essential component of any organization’s cybersecurity strategy, whether it is a business, a government institution, or an individual user. Access security not only protects technological infrastructure but also helps comply with security regulations and standards, which is crucial for maintaining customer trust and organizational reputation.
