A key component to any cybersecurity program is management of the “day to day” operations.
Instructions for Initial Post:
Thinking about what needs to take place at an organization regarding cybersecurity operations, list out at least three (3) periodic checks that should take place either on a daily, weekly, monthly or quarterly basis. In this list, detail WHY the activity needs to take place and what the expected/desired result should be if things are operating successfully.

Implementing regular checks to guarantee the continuous protection and integrity of information systems is necessary for a business to maintain strong cybersecurity operations. Regular inspections are essential for fast threat identification and reaction. By checking firewall and intrusion detection system (IDS) logs on a regular basis, one can detect any security events early on and take prompt action in response to any suspicious activity or unauthorized access attempts. The goal is to make sure that all logs are examined without any indications of erroneous or malicious activity, and that any anomalies found are quickly looked into and fixed. Daily antivirus and anti-malware scans are also necessary to keep system integrity intact by finding and eliminating any new viruses or malware that may have gotten past first defenses. The goal is to finish the scans without finding any new risks; if any are discovered, they should be isolated and eliminated before looking into the source of the infection.
Ensuring the dependability and security of systems and data is the main goal of weekly checks. It is ensured that data can be properly restored in the event of a ransomware attack, hardware failure, or data corruption by routinely validating backups. The anticipated outcome is full and working backups, with any problems fixed and preventative actions taken to guarantee continued dependability. A weekly evaluation of patch management is also necessary to safeguard systems from the most recent exploits and vulnerabilities. To reduce the possibility of exploitation due to unpatched vulnerabilities, all systems should have the most recent fixes installed.
The purpose of the monthly checks is to keep security measures up to date with organizational modifications and new threats. Monthly user access evaluations lower the risk of insider threats and unauthorized access by ensuring that only authorized individuals have access to critical data. The goal is to preserve the least privilege principle by ensuring that access privileges are in line with present work duties and that any superfluous or out-of-date permits are eliminated. Additionally, keeping security policies up to date and relevant in the face of evolving risks and business needs is ensured by routine reviews and updates. The anticipated outcome is that policies are current, understandable, and practical; staff members are informed of any necessary modifications, and compliance is tracked.
Quarterly inspections include in-depth evaluations and drills for readiness. Regular vulnerability assessments and penetration tests assist in locating and fixing possible gaps in the organization’s security posture before attackers may take advantage of them. A thorough report outlining any vulnerabilities is the intended result, along with remediation actions to fix found problems and enhance the security posture in following testing. Furthermore, by testing the incident response strategy on a regular basis, the company may minimize potential harm and recovery time by ensuring that it is ready to address cybersecurity incidents. The anticipated outcome is a well-trained incident response team, a well-executed response strategy, and the identification and correction of any weaknesses or potential improvement areas.
Through the implementation of these regular assessments, companies can greatly improve their cybersecurity operations. The organization’s overall security posture is strengthened by this proactive strategy, which guarantees the identification and mitigation of possible threats, data integrity, and compliance with security policies and best practices.

Vulnerability management is a key ongoing effort that should be part of all cybersecurity programs. Identifying the configuration of assets and patches required is an important hardening activity.
Instructions for Initial Post:
A vulnerability management program can be wide and detailed, requiring tools and process in order to be successful. What are three activities required of a vulnerability management process that are critical for success? Don’t consider exact tools or technology at this point, the goal is to flesh out the overall key process steps. Describe them and give some details on those activities based on best practices.

Agree or Disagree? Why?
1) Asset Identification and Performing Vulnerability Scan
When thinking about vulnerability management one of the first things thought about should be “What does the organization have that is vulnerable?” This is where maintaining a list of assets is crucial for the success of vulnerability management. Having a list of assets and keeping those assets updated when completing a vulnerability scan is a practice security teams should be prioritizing so there is a reflective date and time of when a scan was last performed and on which assets it was performed on. Other information should be kept in the asset list as well such as the version of the asset, what patches have been performed already, and maybe even setting configurations. Performing a vulnerability scan could be another step in the management process, but including it here seemed important. Performing the vulnerability scan should also confirm which assets in the asset list are functioning. If you perform a vulnerability scan on a system and it does not show up but is in the asset list, you might have a problem or documentation is not correct. The scan will identify information such as open ports, which services are running, and find known vulnerabilities in the systems (Rapid7, 2020).
2) Assess Vulnerability Risk and Prioritization
Once vulnerabilities are identified, it becomes important to assess the risk of each vulnerability to ensure the vulnerabilities are dealt with accordingly. Vulnerability management platforms such as CVSS (Common Vulnerability Scoring System) will provide scores and risk ratings based on the severity of the risk. According to Rapid7 (2020), some risk assessment factors are as follows: “Could someone exploit a vulnerability from the internet, what is the difficulty of exploiting a vulnerability, what would the impact on the business be if this vulnerability was exploited, how long has the vulnerability been on the network?” etc. When prioritizing these vulnerabilities is is important to keep in mind aspects such as asset exposure, how available the asset it, and how critical the asset is to the organization (Rapid7, 2020).
3) Address/Remediate and Mitigate
Rapid7 (2020) gives great insight on different ways to treat vulnerabilities which are: Remediation, Mitigation, and Acceptance. Remediation is completely fixing or patching a vulnerability so it can not longer be exploited and is the outcome most organizations would like to have. Mitigation efforts is lessening the probability of a vulnerability being exploited which should be done when fix or patch is not ready available. This is not a full proof remediation effort as the vulnerability could still be exploited. Acceptable is the final way to treat vulnerabilities. This effort is only justified when a vulnerability is considered a low risk where the cost of fixing the vulnerability is much greater than the cost that the organization would sustain IF an exploit were to occur. All of these processes are risk reduction measures. One important aspect to keep in mind here is being notified when a risk reduction effort is completed.
