When a legacy device is no longer receiving updates or patches, it is considered to be at the end of life (EOL).
This means the manufacturer has ceased support for the device, and it will no longer receive updates, security patches, or technical assistance. EOL devices pose security risks and are often decommissioned or replaced.
End of support may seem similar but typically refers to the cessation of technical support, whereas EOL means the device is fully retired.
End of business and End of testing do not apply in this context.

The logs show an SQL injection attack. The first step is to verify if new accounts have been created, indicating a successful injection.

Virtual Desktop Infrastructure (VDI) allows a company to host desktop environments on a centralized server.
Offshore teams can access these virtual desktops remotely, ensuring that sensitive data stays within the company's infrastructure without the need to provide physical devices to the team. This solution is ideal for maintaining data security while enabling remote work, as all data processing occurs on the company's secure servers.

If cadets are using company phone numbers to make unsolicited calls, and the logs confirm the numbers are not being spoofed, it suggests that the SIP (Session Initiation Protocol) server's security settings might be weak. This could allow unauthorized access or exploitation of the company's telephony services, potentially leading to misuse by unauthorized individuals.
