Common risks associated with users having unlimited local admin rights
With the wider implementation of new 2nd generation anti-virus, advanced UTM firewalls, intrusion detection and response systems, application whitelisting, or other modern security systems Administrators wonder why remove local Admin rights? Is it necessary? Having these tools and systems in place are good ‘defense in depth’ measures but the reality is that your users/employees and the security on their workstations is potentially the weakest link in your security. Employees although typically well intentioned often can’t tell between good and bad software, or of the negative security impact a setting/configuration change will have until it’s too late. The easiest way to prevent installation of most malware, or to configuration changes that create vulnerabilities is to restrict local admin rights or privileges. Regardless of the other systems that you many have in place it is considered a ‘best practice’ to restrict or remove local Admin rights on user workstations and in various compliance scenarios it is required.
Removing Local Admin Rights Will Help Close the Gap On External Threats
Aside from the concern of an Employee accidentally taking a false step while having Admin privileges is what a malicious actor can do if they are able to compromise one of your user’s login credentials. When your users have Admin privileges potentially any access that is obtained can quickly escalate into a network wide issue. Attackers use native tools in Windows along with local Admin privileges to successfully manipulate local certificate stores to gain trust, bypass other security tools, and ultimately escalate their privileges to gain access to network admin credentials, secured files, data stores, and resources on your network allowing them to carry out any action remotely at will. This not only gives them the ability to gain access but to do so for extended periods of time while remaining undetected with ample opportunity to cover their tracks.
