2021 Guide to Cyber Threat Detection

Effective cyber threat detection requires monitoring network activity for anomalies or matching network activity with known threats.

Effective cyber threat detection requires monitoring network activity for anomalies in network activity or matching network activity with known threats. There are various tools used to detect and monitor cyber threats, but successful cyber threat detection depends on enhanced awareness and increased visibility.

There are many ways to monitor internet and security threats in a secured environment and these include network-based scanning, network-based logging, and system monitoring.

Network-Based Scanning

Network-based scanning involves an analysis of network behavior. One can examine data packets or network flows to identify abnormal network behaviors. Network-based network monitoring involves logging all network traffic. System-level monitoring allows monitoring and detecting of system activity on a network by the administrator.

Network-Based Logging

Network-based logging involves capturing network events and storing them in a logbook. The logs can be read by monitoring devices like network sniffers. System-level network monitoring is an easy way to monitor network-related activities, as it allows monitoring all network processes. This is very useful when network monitoring is done manually, which may be a challenge. These systems are used to collect network and application statistics.

Threat Intelligence Monitoring

Another type of monitoring is threat intelligence monitoring, which uses automated systems to analyze threats and identify risks. This kind of system enables detection, response, and analysis of threats and can be used in conjunction with other types of monitoring systems to build a complete network defense capability.

In the network-based logging scenario, monitoring tools can be installed on machines to gather information about network traffic. The logging tools are designed to identify anomalies in traffic patterns in the network.

System Monitoring

System-level network monitoring allows monitoring of the entire network and can be used in conjunction with other types of monitoring systems. It is important to set up a security monitoring system that has a central monitoring station. This station will have a collection of hardware devices that will provide real-time alerts and messages regarding network activity. It is recommended that network monitoring solutions should use firewalls. to control access to the main network security tools.

Real-time Notification

Real-time notification is one of the most popular options available for monitoring. Real-time notification enables network monitoring through real-time alerts and message streams sent via email, instant messaging, PABX, or VOIP.

Threat intelligence monitoring is also a viable option for threat management and protection. There are several monitoring systems and tools that are used for this purpose. Some are built to generate alerts when certain conditions are identified.

Monitoring systems that provide real-time alerts and messages enable network monitoring through real-time alerts and messages sent via email, instant messaging, PABX, or VOIP. Real-time alerts enable network monitoring through real-time alerts and messages sent via email, instant messaging, PABX, or VOIP.

Detection Capabilities

These tools also have detection capabilities, which is useful when there is a need to monitor a malicious network. Many systems come with a network monitoring database and network alerting features. Detection capabilities are important to any network management system and can be provided by real-time alerts and messages sent via email, instant messaging, PABX, or VOIP.

A security tool that provides both these features will offer the best protection against security threats. Security systems that include the two features are often integrated into a comprehensive security solution. It is beneficial for network monitoring to have both features, but for some it is more beneficial to have only one feature for network monitoring, while others require both features to be combined.

Other tools that can be used to provide network monitoring include a virus scanning tool and an anti-spyware monitoring system. Most networks require network monitoring through monitoring solutions that use both features. Security monitoring tools are the most effective way to ensure that a system is protected against security threats.

Some types of networks use threat intelligence monitoring. Security monitoring software can include a network threat analyzer and security alert management, which is used to detect threats on a network and determine the potential threats so that you can take measures to prevent the security threats from reaching your system.

Cyber Threat Response

Cyber Threat Response is a security system that monitors and protects networks from malicious attacks. This type of security is designed to help reduce the costs of maintaining the systems as well as reduce the risk of losing critical information. It is often a combination of different technologies. The main components are:

Network filtering devices act like a firewall to restrict the network traffic to specific destinations and/or servers. This device helps identify and isolate malicious activity within the network. A network filter device can also be used to reduce the possibility of the system crashing when infected by a virus or worm.

Firewalls prevent hackers from gaining access to the network. They can also block traffic, detect network attacks, and monitor any suspicious activity in the system.

Intrusion Detection Systems (IDS) act like an anti-virus program and keep an eye on incoming emails. Once it detects a threat it alerts the administrator of the system for proper action. Some IDSs also perform other actions like changing passwords and deleting files and folders.

Anti-virus and anti-spyware programs to help scan the network for harmful elements. Once the scan is complete the administrator may delete unwanted files or folders. These programs will keep a watchful eye on all incoming and outgoing network traffic.

It should be noted that a cyber security system requires continuous monitoring and maintenance. The system must be updated and regularly patched.

The importance of a cyber threat response is that it helps you to minimize the damages caused by a computer attack. If the system is not properly monitored and maintained it may lead to a complete breakdown of the network and loss of sensitive information.

Firewalls

The most important component of the security system is the firewall. A firewall blocks the attack of malicious software through the network. However, sometimes the firewall itself gets blocked. This is usually seen in network attached storage or SAN, which is used by some businesses as an integrated network storage system.

A firewall can be integrated into a network firewall or can be implemented on its own. A standalone firewall has the capability to manage the different systems on the network. The standalone firewalls work by using rules that tell them which programs to allow and which ones to deny.

Firewalls are easy to install. Some firewalls have the ability to be integrated with a router and are easy to configure. These firewalls may be configured through command lines provided by a remote administrator. Some firewalls can be programmed through a console and some are installed directly on the system.

The type of firewall you choose depends on the network you are running and your requirements. There are many kinds of firewalls, including those that are designed for home use, small enterprise networks, or small organizations.

Firewalls should be maintained regularly and periodically upgraded. An effective and reliable firewall is essential to the security of your network.

Firewalls can prevent hackers from accessing your systems. However, they cannot stop a hacker from getting past the security measure. The only way to protect yourself is to maintain a good and tight network defense by using the right firewall configuration. This means you need to monitor your network and have an in-depth knowledge of what you are doing.

Some web applications are vulnerable to hacking. If you can identify and avoid these vulnerabilities, it can give you a very big advantage in the cyber world. You can prevent your website from being compromised by hackers by monitoring your website and all of your network traffic. In addition to monitoring your website, you should also monitor the web traffic on your employees’ computers.

Beginner’s Guide To Endpoint Security Software

Beginner’s Guide To Endpoint Security Software

Endpoint security software can be a critical tool for defending your organization from cyber attacks, vulnerabilities, and ransomware.

[vc_empty_space]
[vc_single_image image=”264202″ img_size=”full” css_animation=”fadeIn”]

In 2018, 62% of businesses experienced a cyber attack, and in the first half of 2019 data breaches exposed 4.1 billion records.

We know that cybersecurity is a problem, but often we don’t know what to do about it, and unfortunately, the statistics show that the vast majority of companies are not prepared for attacks.

And the cause is that most businesses simply don’t know what to do to counter the cyberattacks. The answer is endpoint security.

What is Endpoint Security?

Endpoint security, as the name suggests, refers to securing endpoints. What are endpoints? They are end-user devices, such as computers, laptops, tablets, phones–even smart watches. Any computer that someone uses, no matter how small it may appear, is susceptible to attack and must be secured.

Endpoint security software is used by businesses, as opposed to individuals and homes who generally just use an antivirus software. The difference between a home’s antivirus software and a businesses endpoint security is big, but the main and critical difference is that endpoint security software secures an entire network, with all of that network’s endpoints responding in unison, via the cloud, rather than independently.

[vc_single_image image=”264404″ img_size=”full” css_animation=”fadeIn”]

What Does Endpoint Security Software Do?

When a threat is detected, the endpoint’s user is notified and the software kicks into gear, activating its automatic protective measures. Some of these capabilities include, but are not limited to, antivirus management, integrated firewalls, network access control, whitelisting, intrusion detection and response, and root cause analysis.

The faster a security software is able to counter a threat and begin remediation, the lower the chances are that the threat will both spread and expose more breaches. It lowers the risk of downtime, which lowers the cost of the attack.

What Threats Does Endpoint Security Software Address?

Phishing

Phishing is one of the most common types of cyberattack. The attacker pretends to be someone or something else, trying to get the user to click on a malicious link or enter sensitive data.

For example, a phishing attack may send an email that appears to be from a company you trust, giving you a link to go to their website and login–but the email and website are fake, and by entering your login information you are handing over your login and password to the attacker. This type of attack has been used successfully to get access to corporate computers, to bank accounts, to email accounts, and much more.

Ransomware

Ransomware is an attack that targets the endpoint user’s files on their computer, encrypting them. Once the files have been encrypted, the user will get a ransom demand that they either pay a certain amount to regain access to their files, or the files will forever be lost. Often, these cyberattackers demand payment in the form of cryptocurrency like Bitcoin.

Data Theft

Perhaps the type of attack that gets the most news attention is data theft, where a cyberattacker will enter a user’s system and access data that belongs to the business. Often this data is customer data, including names, personal information, and payment information.

By doing this, the thieves can steal identities as well as sell the credit card or bank account numbers. These types of attack make the news because they impact so many people–often hundreds of millions of customers, such as in the Yahoo! breach, or the Equifax breach.

[vc_single_image image=”38151″ img_size=”full” onclick=”custom_link” css_animation=”fadeIn” link=”https://syxsense.com/start-a-free-trial-of-syxsense”]

What’s the Difference Between Anti-Virus Software and Endpoint Security Software?

The main difference between anti-virus software and endpoint security software is in its scope. Anti-virus software will protect from many of the same things that endpoint security software does, but anti-virus software merely protects a single computer from these threats, its automated services locking down the computer and trying to isolate the problem.

While the anti-virus software may connect online to its company, like Norton or Kaspersky, and get information about the attack from them, it only solves the problem on that specific device.

Endpoint security software, on the other hand, protects the entire network, immediately going into defensive mode to find other malware and viruses. When one endpoint device is compromised, all of the devices are inspected.

Another difference is that endpoint security software is not necessarily installed on every computer, but is software attached to the network, whereas antivirus software is installed on each machine.

What Makes Endpoint Security Software So Important?

Endpoint security software is so important because businesses and organizations are under attack more than they ever have been before. Since 2014, security breaches have increased by 67%, and the average cost of a data breach is $3.92 million.

[vc_single_image image=”84930″ img_size=”full” css_animation=”fadeIn”]

Some of the most notable breaches have been incredibly costly, such as the Equifax breach in 2017, which affected 147 million consumers and cost the company $4 billion.

And lest it be thought that these attacks only happen to big companies with millions of users, it is reported that 82% of small and medium sized businesses have had malware attacks that have successfully broken through their traditional antivirus solutions.

This problem is big, and it is expensive, both in dollars lost and in reputation damaged. And the problem is getting bigger all the time. Malware, viruses, and phishing attacks are all on the rise, and newer attacks, especially targeting mobile devices, are skyrocketing.

By getting an endpoint security system that is prepared for these attacks, companies are able to combat the threat of a single user accidentally infecting an entire workplace through one wrong click. It is far less expensive to act on this threat now, than wait until your computer system is the one under attack, being ransomed, or having been breached.

The Best Way to Patch Linux OS

By Patch ManagementNo Comments

The Best Way to Patch Linux OS

Linux is generally considered a more reliable OS to apply updates to, but not patching will expose your environment just like any other operating system.
[vc_empty_space]
[vc_single_image image=”38835″ img_size=”full” alignment=”center”]

How to Patch Linux

If you ever visit a Patch Tuesday article, you will often find comments about using Linux because of its reliability and lack of updates. This is often a huge misconception in the Linux community. Each Linux OS is different and some of the examples below show updates that are needed only a week after the servers were last fully patched.

Installing individual updates for Linux is relatively easy, but it requires you to know the name of the update you want to install.

The following process takes some time due to the use of the command line scripts. However, we recommend you learn the basics of “bash” (Bourne Again Shell), which is the Unix shell since it will greatly help the understanding of the process.

Both experts and the community are correct that the updates are more reliable with almost no Blue / Black Screen of Death (BSOD), but that doesn’t mean Linux doesn’t need to be updated.

Getting Started

  1. Establish a secure SSH remote console to the server, e.g. Putty or Telnet
  2. Run the following command line: apt list –upgradable | grep “-security”
[vc_single_image image=”31043″ img_size=”full” alignment=”center”]

Understanding the resultant screen shot above is essential, as each line records details of the package name, the version it upgrades to and the version installed. For example, the screen shot includes the following:

apparmor/xenial-updates,xenial-security 2.10.95-0ubuntu2.11 amd64 [upgradable from: 2.10.95-0ubuntu2.10]

Legend

Red: Name of package

Green: Name of upgraded package

Purple: Installed version of package

[vc_separator css=”.vc_custom_1561056820587{padding-top: 10px !important;padding-bottom: 10px !important;}”]

Where is the Severity and Update Description?

If you are used to Microsoft Windows Update (WSUS), you will notice the output of the script only produces the name of the missing update package. In fact, unless you search for the package name on the specific Linux OS website you will never know what are more important than others, or what the package is actually fixing.

Many industry experts believe this knowledge is essential when choosing which to prioritize, especially since many don’t have the time to install packages which are actually not security-related or very low in severity.

On the other hand, how would a Linux administrator know which package fixes a zero-day vulnerability or were absolutely essential to apply? Let’s continue with the install process:

  1. Identify the update(s) you wish to install (copy and paste is really useful)
  2. Run the following command line: sudo apt-get install <package name>=<version> For example, sudo apt-get install apparmor=2.10.95-0ubuntu2.11
[vc_separator css=”.vc_custom_1561056820587{padding-top: 10px !important;padding-bottom: 10px !important;}”]

Security Privileges

Because you are making changes to the system, your account must have SUDO security privileges, e.g. supervisor. Also pay attention to the spaces above as the command line needs to be exact in order to pass correctly to the Unix shell.

If you wish to install many updates at the same time, use a comma and paste the next update onto the line.

If you want to update a package to the latest version and not necessarily the version which has been detected, you can omit the version. However, this is not recommend or considered best practice due to the testing of specific versions of packages on your servers.

For example: sudo apt-get install apparmor

By default, all Linux packages are installed without a reboot.

Linux is generally considered a more reliable OS to apply updates to, but even so, the lack of patching will expose your environment just like any other operating system.

[vc_single_image image=”38151″ img_size=”full” alignment=”center” onclick=”custom_link” link=”https://syxsense.com/start-a-free-trial-of-syxsense”]

Patching Linux OS with Syxsense

Syxsense has many automation benefits to the manual patching methodology above. With the discovery process, all Linux devices can be detected and inventoried. Our Patch Manager displays the packages missing just like the scripts above, only we include additional information that is important to IT managers like the description, the vendor severity, and the independent CVSS score which is the cutting edge of vulnerability severity assessment.

Identifying zero-day updates is made easy with the color coding of the interface. The scheduler used to deploy the updated packages allowed flexible timing and reboot behavior to be set with ease. Enable your Linux Administrator to utilize their resources more efficiently by allowing them to automate and report on the patching of your Linux environment.

The Ultimate Strategy for Server Patching

By Patch ManagementNo Comments

The Ultimate Strategy for Server Patching

Patching server environments is critical for preventing internal and external attacks. Discover the key success factors and strike a balance between effectiveness and efficiency.
[vc_empty_space]
[vc_single_image image=”38745″ img_size=”full”]

Patching for Servers

Remediating server environments is crucially important to secure the environment from internal and external attacks as well as ensure stability and performance. Downtime, duration, and frequency are key factors for patching servers, as well as a healthy balance between effectiveness and efficiency.

When patching servers, downtime must always be minimized. A suitable downtime strategy should be utilized so that reboots are only performed when necessary, ensuring a faster operational turnaround when many updates are needed.

An effective patching strategy requires devices to be successfully remediated with few or no pending issues. It also means that the devices have been targeted with little downtime or resources, but no clear measure of success.

Ensuring an effective and efficient approach allows the end goal (a healthy environment) to be achieved at the lowest cost possible.

Change Management

One important factor in patching and also to achieve an effective remediation strategy is change management. This provides awareness about the upcoming changes in the environment and also to help from an auditing perspective.

Every organization attains a defined process based on their relative business needs. It’s highly recommended to use the Standard Change Template since remediation is a mandatory activity to be performed on a monthly basis.

Scheduling

Frequency and duration are additionally important to ensure efficiency. As mentioned, downtime must be minimized and scheduling appropriately helps to mitigate this risk.

For example, Microsoft recommends patching servers monthly; not quarterly. Plan the various scopes for patching and segregate the environment accordingly, such as Development, then User Acceptance, then Production, then Disaster Recovery.

When taking this approach and preparing any stakeholders/users for downtime, notifications may be sent beforehand so that the audience can best prepare. Gathering all information beforehand also allows for scheduling to be a simple process so that each additional month is easier than the last.

Ensure a proper communication channel is supplied so that there are no surprises.

Compliance and Reporting

Realtime task functionality displays where each and every server device is at its remediation stage, whether detecting, applying updates, or rebooting.

Pre-and Post-patching reports provided in numerous templates, including:

  • Detected Patches by Device
  • Top X Vulnerable Devices
  • Patch Deployment History by Device/Patch
  • HIPAA Compliance
  • SOX Compliance
  • PCI & DSS Compliance
  • Security Risk Assessment

Where Syxsense Manage Fits

Syxsense Manage allows all aspects of the patching process to be easily organized and prepared. Every patching task addresses the high level questions in a step-by-step format: where, what, and when.

Where

By organizing the inventory beforehand, the question of “where” is easily prepared. This also doesn’t need to be re-created every month. Leveraging site locations or dynamic filters based on inventory and/or logical organization data, the question of “where” only needs to be asked on the front-end.

What

Following change management procedures, patch content can be easily organized using patch groups. This ensures only the approved patches are deployed with each scheduled deployment task.

Keeping things easy: skipping an approval strategy can also be done by leveraging Syxsense Manage’s built-in detection logic so that only the applicable updates are deployed where the non-applicable updates are simply skipped.

Patch filters can also be used to dynamically deploy updates that share a common value, such as “Critical Patches”, leaving out the other updates of lower severity.

When

The toughest question is “when” and of course: when is best?

Every organization is different and Syxsense Manage provides multiple avenues for scheduling, such as on-demand, recurring in weekly intervals with missed-task options, as well as formal maintenance windows and blackout hours.

The most widely used option for server patching is maintenance windows. These establish pre-approved frequencies that may be re-used with every following month, but also protecting the users with schedule duration.

Maintenance windows can be scheduled at various times of day, daily, weekly, and monthly.

Reboots

Rebooting servers is where the concept of downtime comes into play.

Reboots can be forced for all, or none; however, reboots will typically be required every single month and must apply to secure the device with the latest updates.

Going back to the “where” step, devices can be targeted based on which require a reboot and which do not, ensuring only those that do will receive the reboot and others will not be touched.

Validating with end-users: although servers may not have an end-user, custom messages and timers can always be supplied so that the reboot may be postponed by the administrator.

Measuring downtime: by using realtime task functionality, Syxsense Manage can always visualize the reboot duration and end user choices.
