Traditional network security relies on a fixed perimeter, typically protected by firewalls. While this isolates internal services, it becomes vulnerable with the rise of: User-managed devices: These devices bypass traditional perimeter controls. Phishing attacks: These attacks can give unauthorized users access within the perimeter.
Perimeter 81 is an Israeli cloud and network security company that develops secure remote networks, based on the zero trust architecture, for organizations. Its technology replaces legacy security appliances like VPNs and firewalls .
A zero trust architecture (ZTA) is an enterprise's cyber security plan that utilizes zero trust concepts and encompasses component relationships, workflow planning, and access policies. Therefore, a zero trust enterprise is the network infrastructure (physical and virtual) and operational policies that are in place for an enterprise as a ...
The military strategy revolves around having a weaker perimeter defense and intentionally yielding space to buy time, envelop, and ultimately counter-attack an opponent, whereas the information security strategy simply involves multiple layers of controls, but not intentionally ceding ground (cf. honeypot.) The onion model of defense in depth
A fence-mounted perimeter intrusion detection system installed on a chain link fence. A perimeter intrusion detection system (PIDS) is a device or sensor that detects the presence of an intruder attempting to breach the physical perimeter of a property, building, or other secured area.
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.
Security controls can also be classified according to the implementation of the control (sometimes termed control categories), for example: Physical controls - e.g. fences, doors, locks and fire extinguishers; Procedural or administrative controls - e.g. incident response processes, management oversight, security awareness and training;
Cybersecurity engineering is a tech discipline focused on the protection of systems, networks, and data from unauthorized access, cyberattacks, and other malicious activities. It applies engineering principles to the design, implementation, maintenance, and evaluation of secure systems, ensuring the integrity, confidentiality, and availability ...
