Physical System Attacks

Physical system attacks refer to a category of security threats and attacks that target the physical components and infrastructure of a computer or information system.

These attacks often involve direct access to hardware, data centers, or other physical assets. 

Types of physical attacks

Unauthorized Access

Unauthorized individuals gaining physical access to a facility or server room can compromise the security of the systems within. This can result in data theft, tampering, or sabotage.

Tampering

Attackers may physically manipulate or tamper with hardware components, such as replacing components with compromised ones, inserting malicious hardware devices (e.g., hardware keyloggers), or altering wiring.

Theft

Theft of physical equipment, such as laptops, servers, or backup tapes, can lead to data breaches or unauthorized access if the stolen devices contain sensitive information.

Dumpster Diving

Attackers may search through discarded documents, equipment, or storage media to gather information or exploit sensitive data.

Power and Environmental Attacks

Manipulating power sources, temperature, or environmental conditions (e.g., overheating) can disrupt system operations or cause hardware damage.

Defense against physical attacks

Access Controls

Implement strong access controls and authentication mechanisms, such as biometrics, card readers, and PINs, to restrict physical access to authorized personnel only.

Surveillance and Monitoring

Use security cameras, motion detectors, and intrusion detection systems to monitor and detect unauthorized access or suspicious activities.

Visitor Logs

Maintain visitor logs and require sign-in procedures for anyone entering restricted areas.

Secure Disposal

Implement secure disposal practices for documents and equipment to prevent information leakage through dumpster diving.

Environmental Controls

Ensure environmental controls like fire suppression and temperature monitoring are in place to protect hardware.

Employee Training

Educate employees about physical security threats and the importance of following security policies and procedures.

Incident Response

Develop and practice incident response plans for physical security breaches.

Inventory Management

Keep track of hardware and equipment inventory to detect theft promptly.

Physical Intrusion Testing

Conduct regular physical security assessments to identify vulnerabilities and weaknesses.
