Remote access security

Remote access security covers the policies, technologies, and controls that safeguard connections from external networks to internal systems. Examples include VPNs, remote desktops, virtual application gateways, and remote SSH connections. It ensures that only authenticated and authorized external users can tunnel into corporate or cloud resources, typically requiring MFA, secure protocols (e.g., TLS), and endpoint compliance checks.

How does it affect identity security?

Many organizations adopt cloud-native solutions for remote access, such as AWS Client VPN, Azure VPN Gateway, or zero trust network access (ZTNA) platforms. These integrate with cloud IAM for user authentication. For instance, a user logs in via SSO with MFA to a cloud-based VPN. The remote user’s device posture might also be checked (corporate device, up-to-date patches). This synergy ensures that if an attacker steals a password, they still face MFA and device verification. IAM can also grant conditional access—e.g., block remote login from certain geo-locations or outside business hours.

Remote access is a prime target for attackers: if they obtain valid remote credentials, they can bypass on-site physical security. Misconfigured remote services (e.g., RDP exposed to the internet without MFA) are frequently exploited. Ensuring strong authentication, continuous monitoring, and least privilege for remote users helps prevent external breaches. Additionally, remote access solutions must log sessions to detect suspicious activity, ensuring accountability for identity usage.

Case study

Attackers exploited a single-factor VPN account to infiltrate Colonial Pipeline’s network, resulting in a major ransomware event that disrupted fuel supply. Strong remote access security (MFA + continuous monitoring) could have blocked the stolen credential’s use.
