An IDS system uses sensors and detectors placed throughout a network to monitor network traffic and identify any suspicious or unauthorized activity, such as attempted breaches, malware infections, or abnormal patterns in data usage. When an IDS system detects a potential threat, it alerts the security team, who can then act quickly to mitigate the risk.

On the other hand, an IPS system takes action automatically when a threat is detected by blocking the malicious activity or quarantining compromised devices before they can cause harm to the network.

Both IDS and IPS systems are monitored by security guards in a central location called a Security Operations Center (SOC). The SOC is equipped with advanced monitoring tools that allow guard to view real-time data from IDS and IPS systems, providing them with an overview of the entire network’s security posture.

If an alarm or notification is triggered by either of these systems, the security guards will analyze it further to determine whether it is an actual threat or a false positive. If deemed necessary, they can then take appropriate actions such as launching an investigation, isolating affected devices from the network, or escalating the issue to higher-level support teams for remediation.

Furthermore, electronic surveillance techniques such as remote access monitoring also enable security guards to monitor remote employees’ login activity and track their virtual interactions in real-time. Any suspicious login attempts or unauthorized access can be immediately flagged and addressed by security personnel.

18.Can you explain the process of conducting a risk assessment for a company’s network, and how it can be used to develop an effective security plan?


Conducting a risk assessment for a company’s network involves identifying potential vulnerabilities and threats, evaluating the potential impact of these risks, and determining the likelihood of them occurring. The process can be broken down into five main steps:

1. Identify Assets: The first step is to identify all the assets within the company’s network, including hardware, software, data, and personnel. This will help to determine what needs to be protected.

2. Identify Threats: Next, potential threats to the network must be identified. These can include external threats such as malware attacks or internal threats like accidental data breaches.

3. Assess Vulnerabilities: Once the threats have been identified, it is important to assess any vulnerabilities that exist within the network that could potentially be exploited by these threats. This can include outdated software, weak passwords, or insufficient security controls.

4. Determine Risk Likelihood and Impact: The next step is to evaluate the likelihood of each threat occurring and its potential impact on the network. This can be done through data analysis, expert opinions, and historical data.

5. Develop Mitigation Strategies: Based on the assessed risks, mitigation strategies should be developed to address any identified vulnerabilities and reduce the overall risk level for the network. These strategies may include implementing security controls such as firewalls and encryption or training employees on secure protocols.

Once the risk assessment is complete, it can be used to develop an effective security plan for the company’s network. This plan should outline specific measures that will be taken to protect against identified risks and mitigate any potential damage in case of a breach. It should also include regular updates and maintenance procedures to ensure ongoing protection against evolving threats.

19.In situations where sensitive data is accessed remotely by employees or contractors working from home, how can security guards ensure the secure transmission of this information over networks?


1. Use Secure Connections: Security guards should ensure that all remote employees or contractors use secure connections such as VPN or encrypted Wi-Fi networks to access sensitive data. This will prevent unauthorized access and ensure the secure transmission of information.

2. Encryption: Sensitive data should be encrypted before being transmitted over networks. This will ensure that even if the data is intercepted, it cannot be read without the proper decryption key.

3. Two-Factor Authentication: Implementing two-factor authentication for remote access can add an extra layer of security. This requires users to have a password and a one-time code to login, making it more difficult for unauthorized individuals to gain access.

4. Restrict Access: Security guards should ensure that only authorized individuals have access to sensitive data, whether they are working remotely or in the office. Access controls should be in place to limit who can view, edit, and share sensitive information.

5. Regular Software Updates: Make sure all systems and software used for remote access are up-to-date with the latest security patches and updates. Outdated software can leave vulnerabilities that hackers can exploit.

6. Secure File Sharing: When transmitting sensitive files over a network, security guards should make sure to use secure file sharing methods such as password-protected links or encrypted email attachments.

7. Screen Sharing Restrictions: If employees need to share their screen with others while working remotely, security guards should ensure that screen sharing is restricted only to authorized individuals within a secure virtual meeting platform.

8. Regular Monitoring: It is crucial to regularly monitor network activity and look for any suspicious behavior or attempts at unauthorized access. Security guards can set up alerts for any unusual activity on the networks.

9. Employee Training: Ensuring that all employees are properly trained on remote work best practices and security protocols is essential in maintaining the confidentiality of sensitive data while working from home.

10.Security Audits: Regularly conducting security audits can help identify any potential vulnerabilities and ensure that all security measures are up-to-date and effective in protecting sensitive data during remote access.

20.What measures should be taken by security guards when handling physical devices such as routers, switches or servers that are essential components of a company’s network infrastructure?


1. Familiarize themselves with the devices: Security guards should have a basic understanding of the different types of devices and their functions in the network infrastructure. They should also be aware of any special handling instructions or protocols for each device.

2. Follow proper handling procedures: The security guard should handle the devices with care and follow instructions for proper handling provided by the manufacturer. This includes avoiding rough handling, excessive bending or pressure, and exposure to extreme temperatures or humidity.

3. Keep the devices secure: Physical security is essential for protecting network devices from theft or tampering. Guards should ensure that all doors, cabinets, and racks containing these devices are kept locked at all times.

4. Monitor access to devices: Only authorized personnel should have access to critical network infrastructure components such as routers, switches, and servers. The security guard must monitor who is entering and exiting areas where these devices are stored or installed.

5. Keep a record of equipment movement: The security guard should maintain a logbook of all equipment moved in and out of storage areas or rooms to keep track of their location at all times.

6. Check for signs of tampering: Regular inspections should be conducted on network devices to look for any signs of tampering such as altered configurations, missing cables, or unauthorized changes in equipment placement.

7. Report suspicious activity: If the security guard notices any unauthorized individuals attempting to access network devices or suspicious behavior around them, they should report it immediately to IT personnel or their supervisor.

8. Use proper tools when performing maintenance: When performing routine maintenance tasks on network devices, guards should use appropriate tools recommended by the manufacturer to prevent damage or disruption to operations.

9. Maintain clean environment: Dust, dirt, and debris can affect network device performance and damage sensitive components over time. Guards should ensure that the area surrounding these devices is clean and free from potential contaminants.

10. Follow protocol in case of accidents: Accidents can happen while handling devices, and the security guard should know what actions to take in the event of damage or malfunction. They should follow established protocol and immediately inform IT personnel or their supervisor.
