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.

10 Ways To Protect Your Organization From Cyberattacks

While your first line of defense is always common sense, there are 10 actions that should be implemented to secure your organization.
[vc_empty_space]

This article originally appeared on ypo.org.

Many CEOs don’t want to think about cybersecurity. That’s why you hire a chief technology officer (CTO) or chief information security officer (CISO). But cybersecurity is now a board-level issue. While your first line of defense is always common sense, below are 10 actions every CEO should be implementing to secure their organization, with the help of the IT team.

 

1. Enable Two-Factor Authentication

If it has a password, make sure it supports two-factor authentication, which is a one-time code that is sent by SMS Text, email or an app on your phone like Google Authenticator (we don’t recommend SMS Text). A password is no longer enough to protect yourself. Passwords can be compromised by phishing attacks (emails asking you to enter your password) or stolen from other websites, where you might reuse the same or similar passwords.

Many companies now use Microsoft Office 365 for email and will often synchronize this with local usernames and passwords (Active Directory). If you have a breach in Microsoft Office 365, not only is Office 365 exposed, but now the attacker may have access to your local physical network.

 

2. Use Products Like Duo to Allow Two-Factor Authentication

Today Microsoft Windows and Apple Mac operating systems do not have two-factor authentication to control logons to laptops, desktops, servers, RDP, etc. By implementing tools like Duo (recently acquired by Cisco) you can add a second factor to all your physical and virtual devices. As an added bonus, you can also limit which devices accept a user’s logon.

 

3. Use a Password Manager

It is vital to have different passwords for every system you use. There have been many large-scale hacks of online services like LinkedIn (164 million accounts stolen), Adobe (152 million accounts stolen), Myspace (359 million accounts stolen), and more. This data is being used to create databases of usernames and passwords which can then be used to hack other systems. By having unique passwords for every system, you can protect against this. How do you remember all those passwords? Use a password manager like 1Password.

 

4. Make Sure You Have Backups

Backup everything! If your organization has a breach and ransomware is distributed, make sure you have backups of all your data. By far the easiest way to recover from ransomware is to wipe your devices and restore backups of data.

 

5. Disable SMB Outbound

The U.S. National Cybersecurity and Communications Integration Center (NCCIC) recently issued advice that all organizations should block outbound Server Message Block (SMB) traffic at the firewall – Ports 137/139/445.

A recent hack has been identified that leverages Windows’ ability to automatically logon to remote devices when connecting to a share. This is very useful when connecting to devices within your corporate network, however, it is a huge security hole when used by a hacker.

“Approximately 80 percent of breaches occur because IT has not kept up with software updates.”

7. Limit Access to Everything by Limiting IP Addresses

Many cloud solutions allow you to lock down security by limiting access from only certain IP addresses. For example, you might include your office public IP address and home.

 

8. Instruct Your Accounting Department to Verify Instructions to Pay or Transfer Funds by Phone

An attacker sets up an email address very similar to the CEO or CFO and then sends an email directly to the accounting team instructing them to urgently pay an invoice by wire. Implement a policy that all wires require a phone approval before payment.

 

9. Buy Cyber Insurance

This is a relatively new form of insurance and we have seen it being included in Errors and Omissions policies recently. It is vital that your organization purchases cyber insurance. This will cover the costs of investigation, responding to a breach, as well as business interruption and maybe even reputational losses.

Big Tip: If your organization experiences a breach, as soon as you finish an emergency response — like taking devices off the network — contact your insurance company, a lawyer that specializes in IT security, and let them hire all the IT security investigators. By letting your lawyers hire the IT security investigators, the results of the investigations become privileged information, legally limiting who can access details about what happened.

 

10. Encrypt Confidential Data

Many organizations use services like Dropbox to share and back up data. While these services are great and typically encrypt the data in the cloud, this data can still be decrypted by them. Also, services like Dropbox might sync the data across multiple devices, essentially creating local unencrypted versions of your data.

One approach to protect your data is to use full disk encryption, but you would need to make sure this is enabled across all your devices. Hint: IT management tools like Syxsense will tell you which devices do not have BitLocker enabled. However, this still leaves your data at risk if Dropbox has a breach. Products like BoxCryptor offer the ability to put an extra layer of encryption on the content, which protects your confidential data in the cloud and on local devices.

Patch Everything

Approximately 80 percent of breaches occur because IT has not kept up with software updates. It’s more important than ever to patch all devices, operating systems and applications, and more recently, IoT devices.

Ransomware Disrupts Massive Shipping Company

By NewsNo Comments
[vc_single_image image=”24788″ img_size=”full”]

Cyberattack Causes Shipping Industry Disaster

COSCO, one of the world’s largest shipping companies, has experienced a ransomware attack on their US network. Their Long Beach terminal reported that their website and telephone network went down on July 25.

The company initially downplayed the event, however it quickly became apparent this was much more than a technical difficulty.

There is a legitimate fear this current attack is “a proxy for the entire industry.” Hackers might be testing the waters for lessons learned after the NotPetya attacks in June 2017. The losses and response times will be studied closely by many companies, and future malicious actors.

With the increasing rate of cybercrime, many are starting to accept these attacks as an unavoidable hazard of running a business. But there is a way to combat such threats and mitigate risk. Keeping up to date on patching is the #1 strategy for protecting your company from ransomware.

Syxsense has a comprehensive patch manager. With a quick scan, you can see what devices need updates and the severity of those patches. The deployment task is easily configured and can be set to happen on demand or scheduled around business hours.

There’s a better way to manage your environment. See how with a trial of Syxsense.
