Control work on information security

This control work covers Chapter III. The theory questions are about the three properties of information security, identification–authentication–authorization, the groups of protection means, kinds of network and protocols, symmetric and asymmetric encryption, the electronic signature, the directions of e-government (G2G, G2C, G2B, G2F), the structure of e-mail and the kinds of malware. The practical task is a “Personal security plan”: write an 8-point plan for your own devices and accounts (screen lock, passwords, two-step verification, updates, backup, antivirus, trusted sources, privacy settings). The calculations include the number of password variants, the size of a 3-2-1 backup, file transfer time (size·8 : speed), base64 size (·4/3), small RSA (n = p·q, φ = (p–1)(q–1)) and doubling (2ⁿ). To prepare, repeat the “safety” rules of each lesson, practise spotting a fake address and a phishing message, do the calculations by hand and honestly assess your own safe habits. Note: do not write a real password or personal data in the tasks.
