Vulnerability remediation involves the fixing or patching of cybersecurity weaknesses that are detected in applications, networks and enterprise assets. Before, vulnerability remediation was a manual procedure. Nowadays, it’s more automated with advanced threat intelligence, data science and predictive algorithms assisting security professionals to know which vulnerabilities should be remediated first.
It is essential to remember that the end result of vulnerability management is remediation. One of the vital KPIs of a vulnerability management program is how many high-risk vulnerabilities are neutralized or removed before essential assets, confidential data and systems are compromised.
Why is Vulnerability Remediation Important?
Partners, customers, regulators and employees expect companies to put in place processes and policies that effectively and continuously protect data from malicious loss and accidental exposure. There is also zero tolerance for system slowdowns or disruptions. In short, meeting vulnerability remediation challenges has become an essential business activity.
Where Are Organizations Going Wrong In Terms Of Vulnerability Remediation?
From the onset, many organizations have an outdated idea of what vulnerability remediation involves. It’s not just about scanning your networks for cyber threats. An all-inclusive tactic to vulnerability management includes identifying, reporting, assessing and prioritizing exposures. Most importantly, it also involves risk context.
Instead of just scanning for security breaches, a comprehensive approach to vulnerability remediation shows you how those gaps could be exploited and the aftermath of the occurrence.
Therefore, vulnerability remediation when executed correctly takes a mature approach where all aspects work harmoniously to reduce risk to business-critical assets. That is the objective all IT professionals and IT administrators should follow.
Also, if you start the first principles, you can fail when it comes to implementation. With that in mind, we have highlighted some of the challenges organizations face when managing vulnerabilities.
Failing to Correctly Prioritize Threats
The inability to appropriately rank exposures is one of the most damaging issues that organizations currently face within the context of vulnerability management. Many organizations identify security gaps through scanning, then proceed to the remediation stage. On some level, that kind of urgency is understandable. But it is short-sighted and creates more risk.
IT administrators and IT professionals of different organizations need to focus on prioritization through CVSS. Failure to prioritize it properly may lead to wasted resources as IT teams work towards addressing exposures that pose no real risk to critical business assets.
Risk and threats will make the organization become vulnerable in different ways. The best way to remediate risk is to focus on the percentage of exposures that can be exploited. When it’s done in the right way, this level of prioritization can eliminate 99 percent of risk to sensitive business systems.
What’s the best way to benefit from this approach to prioritization? Using a cutting-edge patch management solution that prioritizes exposures by using attack-centric risk context. An organization can use a tool that goes beyond limited CVSS scoring and shows the full picture of how likely each vulnerability is to be exploited and the risk each exploit poses to the assets.
Not Using a Continuous Approach
The best way to utilize a vulnerability management program is ongoing rather than periodic. If organizations do not take a constant approach, they will struggle to control the flow of vulnerabilities and build up vulnerability debt. That’s a serious issue.
Considering how hard it is to stay on top of emerging vulnerabilities, working with a constant backlog of security issues to address can make the whole situation unsustainable. Instead of irregular scanning and remediation, IT professionals can use an ongoing approach that is centered on automated and continuous vulnerability identification. This is one of the essential ways to develop a robust security posture that is defined by constant improvement.
Poor Communication and Unclear Organizational Structure
When security teams do not have clear lines of communication and the right organizational structure, problems are certain to slip through the cracks. Too often, team members do not have clear roles, and they do not understand where they fit within the overall vulnerability management framework.
When team members have clear roles with well-defined responsibilities, they can work together effectively. Instead of working in isolation and missing the greater picture, each person can work to meet their responsibilities and achieve their specific objectives. Also, they know how their work relates to the roles and responsibilities of others.
Therefore, it’s important that the company’s leadership understand and are fully invested in the program, given how strong cybersecurity has become an essential strategic objective.
Vulnerability Remediation Issues
The consequences of failing to successfully manage vulnerabilities have never been higher. One data breach can lead to financial damage and the number of breaches continues to rise, without fail, every year. Truly, vulnerability remediation has left the realm of being just an IT expenditure – it should be a key business objective.
Therefore, to make that a reality, it’s essential to know that vulnerability management should be a continuous and multi-stage process. It’s also important to address the problems that snare so many smart IT departments to successfully manage vulnerabilities: the lack of organization and communication among teams and leaders.
The approach can pay huge dividends in terms of avoiding these drawbacks. As mentioned above, the best thing that can be done is to incorporate powerful vulnerability management tools that offer proper prioritization guidance and critical risk context.
Once your underlying approach is ideal and you are armed with the right tools, your enterprise will be far ahead of your competitors when it comes to protecting your most valuable assets. It’s also essential to get the services of experienced and professional IT companies that can help you with vulnerability remediation services.

Mitigation and remediation are two words that are used a lot in cybersecurity. Most times they are used interchangeably. Although there is a stark contrast between them, both play a major role in security service providers’ risk-related decisions. In this post, we will take a closer look at both strategies and how threat intelligence contributes to each.
Mitigation Versus Remediation: Knowing the Differences
Remediation and mitigation are both a direct result of risk assessment, following the discovery of a new or advanced persistent threat (APT). Remediation involves the removal of threat when it can be eliminated. On the other hand, mitigation involves creating tactics to reduce a threat’s negative impact when it cannot be eliminated.
Remediation is straightforward because it ascertains attack patterns using indicators of compromise (IoCs). For instance, when a scan catches a vulnerability, it has to be patched effectively in order to prevent malicious individuals from exploiting it. The immediate objective of vulnerability remediation is to stop threats from entering the network by closing security holes.
In mitigation, removing the threat is non-negotiable, as it may lead to service disruption. Mitigation involves conducting risk assessments in order to measure the risk profile of a specific threat and ensure that the remaining risks are acceptable. Unlike remediation, a vulnerability can be left unaddressed for the time being provided it does not present offensive risks or threats.
Once a vulnerability has been discovered, the best solution is to remediate it. In other words, allow IT professionals or IT administrators to fix or patch the vulnerability before it can become a security threat. Generally, it’s the organization’s IT security team, system administrators and system owners who come together to know which actions are suitable.
Remediation can be as complex as replacing a fleet of physical servers across an organization’s network or as simple as applying a readily available software patch. When remediation activities are finalized, it’s best to always run another vulnerability scan to confirm that the vulnerability has been fully resolved.
Nevertheless, sometimes remediation is not possible, for many reasons. Firstly, not all vulnerabilities need to be fixed. For instance, if the vulnerability is identified in Adobe Flash Player but the use of Flash Player is already disabled in all applications and web browsers company-wide, there is no need for action. Also, sometimes you may be prevented from taking remediation action by a technology issue, where a patch is not yet available for the vulnerability in question.
Other times, you may experience setbacks from your own organization. This often occurs when a vulnerability is on a customer-facing system and your company wants to avoid the downtime needed to patch a vulnerability.
In those cases, the concept of mitigation will come into play. That’s a process that reduces the likelihood of a vulnerability being exploited. For instance, distributed denial-of-service (DDoS) mitigation can route suspicious traffic to a centralized location where it is filtered.
Generally, mitigation is not the final step in dealing with a vulnerability. It’s more of a way to buy time for the company to either wait for the technology to be released or find a more suitable time to schedule downtime in the system. In the long run, fixing a network security issue is better than blocking the port that could expose it.
How Mitigation and Remediation Figure in the Kill Chain
Nowadays, organizations know better. Rather than assume their applications are impenetrable, they are searching for proactive ways to uncover ongoing attacks through computer forensics, penetration testing or threat intelligence.
Therefore, many IT security experts understand that they need to go beyond the kill chain model to more effectively address attacks. Their solution is through mitigation and remediation techniques guided by the fact that attacks do not stop with interruption.
Let’s take a closer look at the steps in a kill chain:
Reconnaissance: Attackers research the target by looking at public Internet records for expired domains or certificates they can use for attacks.
Weaponization: Once weaknesses are spotted in the target’s network, cyber attackers create the payload they will use to infiltrate defenses.
Delivery: This is the actual act of delivering a malicious payload. Links embedded in spam, phishing emails or malware-laced email attachments are normally used.
Exploitation: This only occurs when attackers choose to enter a network by abusing a vulnerability in a system or connected device.
Installation: Attackers install malware on a vulnerable system in the network to elevate access privileges, steal data or gain control.
Command and Control: This involves the use of a command and control server to communicate with infected hosts within the target’s network.
Actions on Objectives: Attackers deliver the final blow to the target network, often by exfiltrating data or shutting down operations.
Knowing the elements that make up the kill chain allows cybersecurity professionals to take the right action to prevent attacks. Incident responders can redirect bad traffic to black holes during an ongoing DDoS attack. Additionally, if a similar incident occurs in the future, the best practices they followed in the past can be reapplied, reducing damage and downtime.
How Threat Intelligence Improves Both Processes
IT security experts depend on threat feeds to offer actionable intelligence for their mitigation or vulnerability remediation techniques. Threats are often documented in publicly available databases. To make sense of innumerable datasets, they can use aggregated threat intelligence for faster mitigation and remediation. External data feeds give cybersecurity specialists access to accurate and real-time information which include the following:
Secure Sockets Layer (SSL) vulnerabilities and misconfigurations that could be signs of malicious connections.
Domain infrastructure data that reveals registrants, organization data, email addresses and other information, which may be tied to ongoing publicized attacks.
Reputation scores to know how safe or unsafe accessing a particular domain is.
A list of domains that resolve to a particular IP address and could reveal ties between both known and unknown malicious hosts.
Threat intelligence empowers security experts by giving them access to structured data to support their remediation and mitigation processes. While policy exceptions and other controls may hold them back from implementing remediation methods, threat intelligence enables them to gain better visibility into all potential attack vectors.

A Service Level Agreement (SLA) is a document that details the expected level of service guaranteed by a vendor or product. This document generally sets out metrics such as uptime expectations and any payoffs if these levels are not met.
For example, if a provider advertises an uptime of 99.9% and exceeds 43 minutes and 50 seconds of service downtime, technically the SLA has been breached and the customer may be entitled to some type of remuneration depending on the agreement.
What do we want SLAs for?
A Service Level Agreement (SLA) specifies the quality of a service. It is a way of defining the limit of failures or times in which the response to a service is measured. Each service measures its quality in a different way, but in all cases it refers to times, and therefore it can be measured.
For example, if you worked in a restaurant, you would define your customer service SLA with several parameters:
Maximum time since a customer sits at the table and is served by a waiter.
Maximum time since you order the drink and it is served to you.
Maximum time since requesting the bill and paying.
Suppose that in our restaurant, we consider that the most important thing is the initial attention, and that no more than 60 seconds can go by, from when you sit down to when you are served. If we had a fully sensorized business with IoT technology, we could measure the time from when the customer sits at a table until a waiter approaches the table.
That way, we could measure the number of times each waiter manages to serve a customer in the established time. The way to do it can be more or less simple, but let’s keep it simple, suppose that every time they do it in less than 60 seconds they comply and when they do not make it, they do not comply. So if out of ten clients they serve in an hour, they fail only with two, they would be 80% compliant. We could make the average of their entire work day and thus easily compare different employees to find out which one has more “quality” in the metric of “serving a customer when they sit down.”
If we use a monitoring system, we could notify their manager every time that the overall quality of the service drops below 80% and by generating automatic reports, we could each month reward those with the best service compliance percentage and take measures (or fire) for those who are doing it worst.
One of the most important functions of monitoring systems is to measure. And measuring service compliance is essential if we care about quality. Whether we are on the provider side or on the client side.
If you are paying for a service, wouldn’t you like to check that you are actually getting what you pay for?
Sometimes we do well not to trust the measurements of others, and it is necessary to check it for “ourselves.” For this, monitoring tools such as Pandora FMS are essential.
What is the «uptime» or activity time?
Uptime is the amount of time that a service is available and operational. It is generally the most important metric for a website, online service, or web-based provider. Sometimes uptime is mistaken with SLA, but uptime is nothing more than a very common metric in online services that is used to measure SLAs, not an SLA, which as we have seen before is something much broader.
The trade-off is downtime – the amount of time a service is unavailable.
Uptime is usually expressed as a percentage, such as “99.9%”, over a specified period of time (usually one month). For example, an uptime of 99.9% equals 43 minutes and 50 seconds of inactivity.
What are the typical metrics of a supplier?
Those that are agreed between the supplier and the client. Each service will have its own metrics and indicators. Thus, in our Monitoring as a Service (MAAS) we can establish several parameters to be measured, among others, let’s see some of them to better understand how to «measure the service quality» through SLA:
Minimum response time to a new incident, 1 hr in standard service.
Critical incident resolution time: 6 hours in standard service.
Service availability time, 99.932% in the standard service.
When we talk about a time percentage, it generally refers to the annual calculation, so 99.932% corresponds to a total of 5h 57m 38s of service shutdown in a year. We can use our SLA calculator (below to test other percentages).
On the contrary, 1hr would be the inverse calculation, and for this we can use online tools such as uptime.is. By using it we will get that six hours would correspond to:
Weekly reporting: 99.405 %
Monthly reporting: 99.863 %
Quarterly reporting: 99.954 %
Yearly reporting: 99.989 %
Similarly to the initial waiter example, we can measure compliance with a support SLA by measuring the sum of several factors, if all are met, we are meeting the SLA, otherwise we’re not. This is how Integria IMS measures it, the helpdesk component integrated in Pandora FMS. Pandora FMS clients use Integria for support, and thanks to it we can ensure that we attend to client requests on time.
How to calculate the service SLA time?
Use our online calculator to calculate a service downtime. For example, test 99.99% to see the maximum downtime for a day, a month, or the entire year.
How can Pandora FMS help with SLAs?
Pandora FMS has different tools to exhaustively control the SLAs of your client/supplier. You have SLA reports segmented by hours, days or weeks. That way you can visually assess where the defaults are.
This is an example of an SLA report in a custom time range (one month) with bands by ranges of a few minutes.
There are reports prepared to show the case of information sources with backup so that you can find out the availability of the service from the customer’s point of view and from the internal point of view:
This is an example of a monthly SLA view with detail by hours and days:
This is an example of a monthly SLA report view with a weekly view and daily detail:
This is an example of an SLA report view by months, with simple views by days:
Service monitoring
One of the most advanced functions of Pandora FMS is monitoring services with Pandora FMS. It is used to continuously monitor the status of a service, which, as we have seen at the beginning, is made up of a set of indicators or metrics. This service often has a series of dependencies and weightings (there are things more important than others) and all services have a certain tolerance or margin, especially if they are made up of many elements and some of these are redundant.
The best example is a cluster, where if you have ten servers, you know that the system works perfectly with seven of them. So the service as such can be operational with one, two or up to three machines failing.
In other cases, a service may have non-critical elements, which are part of the service and that we want to control, even if the service is not affected:
One of the advantages of service monitoring is that you can easily get the route to failure, literally being able to find the needle in the haystack. When you talk about technology, the source of a problem can be somewhat tiny compared to the amount of data you receive. Services help us determine the source of the problem and isolate ourselves from informational noise. They also allow to monitor the degree of service compliance in real time and take action before the quality of the service for a customer is affected.

Much to our detriment, new software vulnerabilities are discovered on a daily basis. For security professionals and companies alike, this becomes a significant concern. Companies must be able to follow a procedure to guarantee that they do not fall prey to these flaws.
Vulnerability and patch management strategies are the best ways to do this. This post discusses key areas where security professionals can concentrate their efforts in order to establish these programs.
The Vulnerability Management Process: Summarized
Vulnerability management, according to the SANS Institute, is the process of identifying, eliminating, and mitigating the inherent risk of vulnerabilities. The goal of a vulnerability assessment program is to develop controls and processes that will help the company discover weaknesses in its technological infrastructure and information system components.
This is critical because attackers may attempt to exploit these flaws in order to obtain unauthorized access to the organization’s systems, disrupt company operations, and steal or leak important data.
When vulnerabilities are discovered, the best method to protect against them is to apply patches that correct the flaws, if any exist. The goal of a company’s patch management policy and program is to define the controls and processes that will protect the company from the vulnerabilities and threats discovered by the vulnerability assessment program. These vulnerabilities and dangers might jeopardize the information system’s security and the data entrusted to it.
What is Security Remediation?
The next essential stage in vulnerability management is security repair. It focuses on lowering security risk by closing security gaps as soon as feasible so that bad actors can’t infiltrate systems. “What is a vulnerability repair process?” you might wonder.
Vulnerability tasks involve assessing the vulnerabilities discovered by your scans, assigning risk levels based on their criticality and potential impact on your environment, preparing responses, and monitoring actions. Vulnerability remediation best practices include:
Maintaining a single source of truth for all vulnerability management teams, including security professionals, IT experts and DevOps.
Attempting to automate as much as possible in order to expedite and enhance remediation.
Incorporating service ticket monitoring in the mix.
Creating remediation playbooks that are specific to your organization’s environment.
Using your scanning tool to give the engineers who are doing the remediation access to information about the vulnerabilities.
Vulnerability Remediation Guidelines
The following are 5 ideas for implementing controls that will help companies build a regularly configured environment that is safe against known vulnerabilities.
1) Establish a Threat Monitoring Strategy
It’s critical for your security staff to remain up to date on the threats that could exploit your company’s information. They accomplish this through evaluating vendor notifications of threats, patches, and system upgrades, as well as receiving information from US CERT, which is always up to date with the most recent information. Any risks discovered by the team must be handled by the vulnerability remediation management.
2) Assess Vulnerabilities on a Regular Basis
This isn’t something you do once and never think about again. Because the evaluation is simply a snapshot of your position at a certain point in time, it might alter when new vulnerabilities are uncovered. As a result, you must design a structured program with clearly defined roles and responsibilities that focuses on the development and maintenance of effective vulnerability protocols and procedures.
3) Create and Maintain a Set of Baseline Setups
Using documented settings and appropriate regulations, standardize the setup of similar technological assets throughout your organization. Your security team must ensure that all baseline configurations in your environment are documented, that these papers are maintained and up to date, that they are incorporated into your system development process, and that they are enforced across your organization.
4) Remediate Vulnerabilities
This is the process of assessing the vulnerabilities you’ve discovered, assigning risk to them, preparing responses to them, and then logging any activities done to mitigate the vulnerabilities you’ve discovered. Finding flaws and doing nothing about them is pointless and leaves your company vulnerable to a variety of threats.
5) Patch Vulnerabilities
The following is the best way to manage vulnerabilities and patches:
First and foremost, you must have processes in place to identify and validate vulnerabilities utilizing suitable tools and services that will assist you in identifying a potential or confirmed danger to your company.
Next, you analyze your findings in order to thoroughly understand what the risks are. Without genuine knowledge, how can you put the proper measures in place to deal with them? After you’ve completed your analysis, you’ll need to remedy the issues.
Once your “repair” is in place, you must rescan or retest to confirm that it took effect and that it was successful. By following these recommendations, you’ll be well on your way to protecting your company against vulnerabilities and dangers that may cause significant harm if not addressed.
How Do You Manage Vulnerabilities?
The identification of your systems’ vulnerabilities is the first step in the vulnerability management process. You may accomplish this using a variety of scanning programs. It’s critical to conduct these scans on a frequent basis since new vulnerabilities emerge all the time. It’s not simple to stay on top of weaknesses.
According to an ESG poll, keeping up with the number of vulnerabilities is one of the greatest vulnerability management issues for 40% of cybersecurity and IT professionals. Perhaps this is why IT experts claim that submitting a report with thousands of vulnerabilities to the operations team to repair is one of the most prevalent ways to fail at vulnerability management.
Successful vulnerability management methods, they say, involve using sophisticated prioritizing approaches and automated workflow technologies to streamline the handover to the repair team.
