It’s no surprise that attackers are using more sophisticated techniques to target systems from personal devices to all sizes of businesses. Deloitte estimated that a low-end cyber-attack costing $34/month could return $25K while larger attacks costing a few thousand dollars could return as much as $1 million per month. IBM estimates the average cost of a data breach to a business as $3.86 million. To mitigate the harm caused by data breaches, you need to know what to monitor and why. Here are ten cybersecurity monitoring suggestions to protect networks, devices, and programs and information from attack, damage, and unauthorized access.
Security Incidents and Impact
The number of reported incidents should be measured to stay aware of cyberattacks. Not every incident leads to a costly data breach. The first step is to calculate the threat percentage of major and minor incidents. Then the average cost of an incident can be determined. Once the numbers of how cybersecurity and data breaches are impacting the company are known, the big picture of annual loss expectancy can be discussed.
Annual Loss Expectancy = (Number of Incidents per Year) x (Potential Loss per Incident)
The annual loss expectancy can change, though, as data breaches and the costs of cleaning up a data breach rise, which requires adjustments to the calculation. Third-party tools can be helpful in detecting and monitoring all applications to see trends in incidents.
Number Security of Incidents
The number of both small and major security incidents is important to measure to remain informed of exploitation and set key performance indicator priorities. If you have the number of security incidents, it is possible to focus on the incidents that have the most significant financial impact on the company. Some hackers are targeting areas for a catastrophic loss. For example, the WannaCry attack is predicted by experts to have created $4 billion in damages, and hospitals were shut down during recovery. While the smaller incidents may not be catastrophic, the alert team should detect and disarm these threats before damage is done. Minor incidents typically include things like suspicious emails and activity on the server from hackers that may try to take down your website.
Time to Resolve an Incident
Time to resolve an incident is essential to measure to learn how the cyber team is performing and measure business impact. Time is money, and cybersecurity is no exception. A log should be kept documenting the time that the breach was first noticed until the final report. Third-party vendor tools can support the logging and interpretation of this time. Downtime can hurt a business from loss of sales to customer confidence. Server logs and hosting providers can help identify data, and traffic issues can provide insights into how much potential damage was caused by the hack. Both the mean-time-to-identify and the mean-time-to-respond should be measured as poor performance in these areas can be a contributor to breach costs. For US companies in 2017, the mean-time-to-contain was 208 days, and the mean-time-to-identify was 52 days.
Number of Systems with Known Vulnerabilities
Knowing the number of assets that have vulnerabilities helps determine the risk that the business could incur. While managing updates and patches can sometimes be complicated, it is vital to avoid loopholes that could be used by hackers. A vulnerability scan should be performed that includes all the assets that indicate what can be done to improve the security of the business.
Invalid Log-In Attempts
It is important to check system logs from time to time to see if anyone has tried to access your computer. It is good to have a system that monitors every attempt to login and tracks, whether it is successful or otherwise. It is good to monitor failed and locked on logon attempts for the entire domain. Software like ADAudit Plus, Netwrix Account Lockout Examiner, and Security Onion can help with these goals. Software like UserLock allows users granulated access restrictions by specific areas like workstation, device, IP, and range. They also can limit for concurrent sessions, enforce user logon times, use real-time user access monitoring, create alerts and rapid response to inappropriate login behavior, remove disconnection from sessions left open as well as report and audit all access events.
Number of Users with “Super User” Access
Employees should have an access level to company resources that are necessary for their work. Identifying the access levels of network users allows them to be adjusted as needed by blocking any super users that have access, but it is not required to perform their job.
Number of Communication Ports Open During a Period of Time
Generally speaking, it is standard to avoid allowing inbound traffic for NetBIOS. Also, businesses should be observant of outbound SSL since a session that stays active for an extended time could be an SSL VPN tunnel that allows bi-directional traffic. Any common ports for protocols that would enable remote sessions should be monitored for the length of time.
Frequency of Access to Critical Enterprise Systems by Third Parties
Managers may grant access to third parties on particular activities. It is critical to monitor whether the access is canceled at the end of the provided service. If this is not measured, there is a chance that the third party returns to extract data or carry out other hacks. And, if the third party’s network is hacked, it exposes the network to the same threat.
Percentage of Business Partners with Effective Cybersecurity Policies
Companies that provide services to your business cannot be overlooked. Providing access to environments to outsourced companies can post a risk if there are not effective cybersecurity policies in place. Your security practice is as strong as the third parties that are connected to your system.
Meeting Regulatory Requirements
It is essential to measure this because there are national regulatory requirements as it relates to cybersecurity incidents. If the business is naïve to understanding current regulations and requirements, it does not relieve the firm of liability and can result in fines as well as reputation costs. States like New York, for example, require financial service companies to hire a CISO responsible for risk mitigation. Data breaches also have requirements that are time-bound for businesses.
Key performance indicators (KPIs) can help a company keep objectives at the forefront of decision making. This overview provided ten suggestions for measuring KPI’s that can help in mitigating risks by measuring your performance against your cybersecurity goals.
