Organizations such as the National Institute of Standards and Technology (NIST) are actively proposing anIdentify-Protect-Detect-Respond-Recoverframework for cybersecurity.
The NIST framework advocates the identification of key business risks due to cyber threats; the protection of data, devices, and services from these threats; continuous monitoring to enable detection of cybersecurity events as they happen; and the development of a clear response and recovery process.
The protection of data, devices, and services can be successful only if the network-connected software and hardware implement an appropriate amount of defensive measures to ensureintegrity,confidentiality, andavailability.
The integrity of a system is compromised when the software is maliciously modified or taken over by an attacker who has learned an administrator-level password. Software defects that permit buffer overflow, database code injection, and cross-site scripting vulnerabilities can also cause a loss of integrity.
Goal:To ensure data and the function of the system are not maliciously or inadvertently manipulated.
No backdoor administrative or maintenance access accounts
Signed and encrypted firmware
Disabling access to the operating system
Fully encrypted control communication
Transport Layer Security Secure Remote Password (TLS-SRP)for client-server connections
Automatic firmware updates
A system’s confidentiality is compromised when users circumvent a system’s access controls to gain unauthorized access to the data it contains. Most often, a breach in confidentiality is the result of an attacker guessing or obtaining a legitimate user’s password to access the system.
Goal:To keep information private and secure.
Centralized user control through Active Directory integration and/or parent/child user sharing
Password strength enforcement
Ability to bulk-change camera passwords fromAvigilon Control Center (ACC)™ video management software
Lock-out on multiple invalid login attempts
In addition to loss of confidentiality and integrity, the availability of a system and its data can be compromised by external attacks. These usually take the form of a denial of service (DoS) attack where an attacker bombards a system with requests. Although it is difficult to protect against all forms of these attacks, the effect is usually temporary.
Goal:To ensure system uptime and continuity of function.
Progressive back-off on multiple invalid login attempts
Separate, limited-access gateway for thin client (web and mobile) access to video
802.1x device authentication
