Cyber Defense (17)

Introduction to Configuration Management

Every company owns a variety of hardware components, devices, and software solutions that run on them. While it is advantageous to acquire and develop complex systems or technology that can aid in the accomplishment of critical business functions, it is equally important to properly configure and maintain them. If these systems or software are not properly managed and changes to them are not accurately tracked, then it becomes difficult to respond to security incidents effectively. Configuration management lays the groundwork for an organization’s effective security management program. This article discusses the fundamentals of configuration management, its significance, various elements, its benefits, and various tools to aid in its implementation.

Introduction to Patching

Security patches and software upgrades are the first locations cybercriminals seek for weaknesses in previous versions that they may target. When an attacker notices that an issue has been resolved, anyone who has not applied the solution becomes a target. Having all of your applications up-to-date can minimize the vast majority of known online threats. In this blog post, we age going to learn what is patching, and what is a patch management lifecycle.

Kerberos Attack and Defense Techniques

Kerberos is a network authentication protocol based on client/server architecture. This protocol does not require users to provide their passwords; instead, it relies on tickets and keys for authentication. Kerberos is a commonly employed authentication protocol in Active Directory. Because of its popularity, it has drawn the attention of hackers worldwide attempting to exploit its security weaknesses and crack the protocol. This article goes over some of the most common Kerberos attacks, how to carry them out, and how to defend against them.

An Explanation of Knowledge and Behavior-Based Detection Within an IDS

An Intrusion Detection System (IDS) is a type of security device that analyzes data packets and compares them against known signatures. The goal of an IDS is to detect intrusions before they cause damage. In this blog post we will explain how an IDS can identify harmful events using Knowledge-based detections and Behavior-based detections, along with the different aspects, benefits, and drawbacks.

The Importance of Security Training and Awareness

Security awareness is a necessity for security training. Improvements in user activity are required for the optimal adoption of a security system. Such adjustments largely consist of modifications to typical job tasks in order to be consistent with the security policy’s standards, rules, and procedures. User-behavior improvement needs some kind of user education. To create and manage security education, and consciousness, all important components must be widely understood. Furthermore, plans of presentation, integration, and execution must also be designed.

Think Your Passwords Are Safe? Think Again

Passwords are frequently susceptible due to where they are kept. You have many options for storage, ranging from plain text to utilizing a password manager. However, an attacker looks at many other places to find any valuable information related to user credentials. For example, auditing files. Your system logs failed password attempts. This generally includes a considerable number of passwords. If you don’t keep them safe, people who come across a recording of failed login attempts may try it for all valid user identities.

Introduction to Honeypots, Honeynets, and Padded Cells

Honeypots, honeynets, and padded cell systems are all terms for a family of sophisticated security solutions that go beyond ordinary intrusion detection. To understand why these technologies aren’t more frequently utilized, first understand how they vary from typical IDPs.

Model Your Threats to Protect Your Assets

Every organization has several valuable assets that must be safeguarded. The assets can be tangible, such as computers, laptops, and network equipment, or intangible, such as information, data, programs, and so on. As the number of cyber-attacks increases around the world, the focus on cyber security is shifting from reactive to proactive methods. A proactive cybersecurity strategy is a preventative strategy that seeks to discover any vulnerabilities and threats surrounding our assets before they have an opportunity to compromise the security of our assets. Threat modeling is one of the most widely utilized proactive methodologies in the creation of secure systems and applications. This article will explain what threat modeling is and how you can leverage it to improve your organization’s security posture.

Weighing the Risks and Benefits of Virtual Machines

When it comes to virtual machines, one of the biggest security threats is the possibility of data breaches. These can occur when unauthorized users gain access to the system, or when malware is able to infect the system. Additionally, virtual machines can be subject to denial of service attacks, which can prevent authorized users from accessing the system. To help mitigate these risks, it is important to implement security measures such as strong authentication and authorization controls, as well as effective malware detection and prevention.

Follow the Separation of Duties Principle for a Safer Organization

One of the oldest security principles still in use today is privilege separation. Simply put, it argues that no single person should have sufficient authority to cause a catastrophic event to occur. Separation of responsibilities guarantees that tasks are distributed to workers in such a way that no single employee has complete control of a process from start to finish. Separation of tasks entails each individual having a separate job, allowing everyone to specialize in a certain area.

Choose the Right Switch for a Secure Network

Switches are an essential component of network security. Switches can help to prevent denial of service attacks and other malicious activity by controlling the flow of traffic. Switches can also be used to segment networks and isolate problem areas. You can better protect your network by understanding how switches work.

Low-security VPN solution: Point-to-Point Tunneling Protocol

If you want to set up a site-to-site VPN, you need to choose the protocol to employ based on functionality and security. In this blog post, we will look at what a point-to-point tunneling protocol (PPTP) is, how it works, and special security considerations.

Practical Windows Hardening: Security Templates

We can strengthen our operating systems in many ways. Today we are going to take a look at the security templates in Windows and how to utilize these tools to protect our environment.

Securing Windows: An Introduction to Windows Group Policy

Many operating system default designs do not supply an optimal degree of security since precedence is given to those who want information access. As a result, it is critical to adjust OS environments to solidify the system for access management. Microsoft supplies a simple way to design and implement Group Policy to groups of computers. With this method, you can strengthen the operating systems and make them less vulnerable to assault.

Stay Protected from Bluetooth Threats

Bluetooth is a widely used wireless technology that enables devices to interact with one another. Unfortunately, it also gives attackers with an opportunity to exploit technical flaws. In this blog article, we’ll go through some of the most frequent Bluetooth threats and how to defend against them. One of the most popular assaults is Bluetooth eavesdropping. An attacker listens in on the conversation between two Bluetooth devices. They can accomplish this by either positioning themselves between the two devices or by employing a gadget capable of receiving and transmitting Bluetooth signals, such as a laptop.

Keep your Data Safe. Encrypt your Wireless Devices

The relevance of safeguarding wirelessly connected devices is increasing as the number of devices connecting to the internet grows. Wireless devices are particularly vulnerable to attack because they are frequently left unattended and easily accessible. You can encrypt your wireless devices and keep your data safe by following a few simple steps.

Don't Let a Corrupt BIOS Ruin your Computer. BIOS Security Helps Keep your Computer Safe

The BIOS is a piece of software that assists with the loading of the operating system on a computer. The machine would be unable to start if the BIOS became corrupted. As a result, it’s critical to maintain the BIOS safety. To help secure the BIOS, there are a few simple steps that may be taken.
