Managed EDR Security is more important in 2019 than it ever has been. Here are our top guides and recommendations for managed endpoint detection and response.
2019 Guide to Managed EDR Security
Endpoints are attackers’ favorite targets. They are the weakest link in your company’s network. In 2017, it was reported that the WannaCry attack exposed the vulnerabilities of 230,000 endpoints around the world. To this end, installing an endpoint detection and response or EDR is a VITAL aspect of cybersecurity for every company that needs to be proactive to modern-day threats.
What is EDR?
EDR is primarily a technology which brings a proactive approach to the issues of cybersecurity. Most traditional products are reactive to security threats—that is not the case with EDR. EDR security does a great job at monitoring endpoints in real time, hunting for threats which have found their way into the company’s defenses. You’ll also get greater flexibility as regards the happenings on endpoints and even the mechanism to help mitigate the attacks.
One of the common tactics synonymous with cybercriminals is the compromise of endpoints, which enables them to create a foothold on the network. With rapid detection and subsequent response to such attacks targeting hosts— laptops, desktops, and servers– you can be a step ahead in securing your IT infrastructure.
What is Managed Detection and Response?
Managed detection and response security is a service that exists because organizations need resources to take into cognizance risks and also improve on their ability to detect and respond to threats.
Companies have a set of tools and procedures that they employ in the detection and response to threats. But all MDR come with similar characteristics:
- MDR is more concerned with threat detection, instead of compliance.
- Services are delivered by using the tools and technologies of the provider—but deployed on the premises of users.
- MDR is highly dependent on security event management and also advanced analytics
- MDR is associated with incident validation and remote response.
Why Choose Managed Endpoint Security?
With the level of cybersecurity breaches, your company’s ability to detect and respond to threat is critical. Lacking the complete picture of what is going on across your environment, might put you in a vulnerable position when threat surfaces.
Managed Endpoint Security Benefits
- Improving detection capabilities—not just network-based monitoring
- Identify threats beyond traditional preventative security
- Finding the root cause of attacks quickly and effectively
- Looking out for threats with suspicious behavioral patterns
- Separating infected hosts from a network
How Secure is EDR?
Technology is increasingly becoming sophisticated, and cybercriminals are also getting better at their game to keep up. Cyber threats are evolving, and antivirus no longer has the same level of protection it once did—detecting suspicious activity and also protecting your device against malware. Cybercriminals are deploying advanced threats to get ahead in this game. Verizon’s 2017 Data Breach Investigations Report puts it that over half of the breaches are malware related, and after one year, their 2018 Data Breach Investigations
It then becomes expedient to actively monitor behavioral events at the endpoint level, which is now the new standard. Using EDR security in conjunction with AV allows you to detect abnormal behavior, including an excellent indicator of compromise which AV solution is not capable of detecting.
3 Types of Attacks That AV Will not detect
- Zero-day attacks
It is as good as it sounds; it opens up as soon as the weakness is established in AV protection. Hence, before a fix is done, it is exploited. AV may detect a malware signature (continuous sequence bytes that is within the malware), but with a zero-day attack manipulation, sneaking past traditional AV is an easy feat.
- Ransomware attacks
Ransomware attacks deal with software downloaded with the help of an unsuspecting victim through an email attachment which has been infected—like a Microsoft word document. AV cannot protect against ransomware; sometimes it is difficult for the signature of malware to be recognized.
- Fileless malware attacks
Fileless malware attacks happen on existing Window tools instead of malicious software that is installed on the victim’s computer. As a result, the AV has no signature to pick on.
Why Managed EDR Security Will Detect These Attacks
Regardless of the kind of malware or virus introduced, EDR security cares less—only cares about the existing behavior. If behavior indicates a suspicious activity, EDR will immediately send alert having identified it. The monitoring of indicators that give a sense of malicious activity will continue to protect against the further threat.
AV protection cannot be relegated to the background, but combining with EDR gives a depth approach as regards your overall security apparatus.
Managed EDR Security to boost Existing Security
MDR is offered to augment the existing security infrastructure and also contain threats that could bypass traditional control. Threats such as network attacks,
Most organizations are more concerned with where threat enters and exit the network. But most often than not the lateral movements of threat is less attended to when they enter the system.
Managed EDR security does not in any way replaces the traditional ant-virus software; it supplements it—works together with anti-virus, blocking obvious threat indicators. These types of security threats cannot be tamed by conventional security controls, especially those associated with continuous detection and also response. EDR cannot block threats but can carry out root cause analysis and possibly identify the devices that have been infected.
Typical use cases for Managed Endpoint Detection and Response
- Identifying and subsequent blockage of Malicious Executables
- Control of executing scripts– where, how, and who
- Managing the use of USB devices and preventing
useof uthe nauthorizeddevices
- Disabled attackers’ ability to use various techniques of
- Prevention of malicious email attachment
- Identify and prevent zero-day attacks successfully.
Merging SIEM with EDR
Organizations are gradually moving from SIEM (Security Information and Event Management)–even the security providers—to EDR (Endpoint Detection and Response). However, it may not be the best decision to take regarding
To speedily understand the full scope of an attack, one could merge SIEM and EDR and monitored from a single console.
Why should we deploy multiple tools—whose integration barely happens—if we don’t have to?
In today world, traditional SIEMs which depends on logs and related correlation rules find it challenging to detect sophisticated attacks. The combination of logs, endpoint data, and network packet, etc., can go a long way to automate threat detection and avail the security team the opportunity to investigate advance attacks. Several SIEM is without this combination or better still, they come up with a weak add-on and assume they have a complete solution. This barely sufficient for your infrastructure and you may soon find yourself in an uncompromising state.
As cyber threats continue to manifest in different ways, your security strategy should be fine-tuned to conform to current challenges. While endpoint security may be vital to your IT architecture, there is a need to ensure that emerging threats and unwanted applications are not jeopardizing your company’s reputation or profits. Having a system that detects and responds rapidly to modern-day threats is indeed undebatable!
