A system usage agreement is a document that defines the rules and expectations for using a company’s IT resources, such as computers, networks, intranets, software, and data. A system usage agreement typically covers topics such as acceptable use, security, privacy, monitoring, ownership, and consequences of violations. A system usage agreement helps to protect the company’s assets, reputation, and legal compliance, as well as the users’ rights and responsibilities. Privacy expectations on a company intranet should be limited to what is stated in the system usage agreement, as the company has the right and the duty to monitor and control the intranet for business purposes. Users should not assume that their activities on the intranet are private or confidential, unless the system usage agreement explicitly guarantees such privacy. The other options, such as precedents, HR policy, and word of mouth, are not reliable or consistent sources of privacy expectations, as they may vary, change, or conflict with the system usage agreement or the law. References: CompTIA IT Fundamentals (ITF+) Certification Guide, page 100; 10 Intranet Best Practices for a Successful Intranet in 2021, point 7.

 WPA2 is the most secure protocol for securing a wireless network and preventing unauthorized access. WPA2 stands for Wi-Fi Protected Access 2, which is an encryption standard that provides strong security and privacy for wireless communications. WPA2 uses AES (Advanced Encryption Standard) to encrypt data and CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) to authenticate data. WPA2 also supports PSK (Pre-Shared Key) and EAP (Extensible Authentication Protocol) methods for verifying the identity of users or devices that connect to the wireless network. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 172.

A certificate is a digital document that verifies the identity and authenticity of a website. A certificate is issued by a trusted authority called a certificate authority (CA). A certificate contains information such as the website’s domain name, the CA’s name, the expiration date, and a digital signature. If a website’s certificate is expired, invalid, or untrusted, the browser will warn the user that the site may not be secure and prompt them to click a link to continue. The user can check the certificate validity by clicking on the padlock icon next to the address bar and viewing the certificate details. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 6, Section 6.2, Page 260.
