Unauthorised access occurs when attackers gain entry to systems, networks, or accounts without permission. Sid doesn’t break doors down – he waits for one left unlocked. Using stolen logins, misconfigured permissions, or weak security controls, he infiltrates systems and accesses data that was never meant to be seen or taken.
-Review access logs regularly and investigate unfamiliar logins
-Use strong, unique passwords and multi-factor authentication
