Official Description

Fundamental principles of computer and communications security and information assurance: ethics, privacy, notions of threat, vulnerabilities, and risk in systems, information warfare, malicious software, data secrecy and integrity issues, network security, trusted computing, mandatory and discretionary access controls, certification and accreditation of systems against security standards. Security mechanisms: authentication, auditing, intrusion detection, access control, cryptography, security protocols, key distribution. Course Information: Same as ECE 422. 4 undergraduate hours. 4 graduate hours. Prerequisite: One of CS 241, CS 341 or ECE 391, or a combination of CS 233 and CS 340.

Learning Goals

Assess and address Security and Privacy (S&P) issues for policy and humans. That is, characterize and classify the threats based on human conformance to policy and evaluate the effectiveness of a range of countermeaures. (1)
Provide S&P risk analysis for basic scenarios based on core principles, specifically the Confidentiality, Integrity, Availability (CIA) requirements. (1)
Apply cryptographic hashes, pseudorandom generators, symmetric, and asymmetric cryptography with appropriate tradeoffs. (1,2,3)
Evaluate options for authentication based on secrets, tokens, and biometrics. (1)
Understand network, application, and systems security. (1,2)
Formulate access control models for basic situations. (1,2)
Write and mitigate malicious code and characterize basic means of its propagation. (1,2,3)
Assess the threat of basic Denial of Service (DoS) attacks. (1)
Provide network securty protections using firewalls and IDSs. (1,2)
Assess threats based on physical layer. (1)
Apply legal and ethical rules for S&P. (4)
