4 Step Guide to OT Security

4 Step Guide to Stronger OT Security


The cybersecurity of industrial systems is becoming a hot topic in today’s headlines. Since connectivity to external networks is being increased significantly, security is becoming the priority in industrial IT and Operational Technology (OT). Many organizations don’t have a reliable cyber defense against their OT assets.

Recently, the Cybersecurity and Infrastructure Security Agency (CISA) and the National Security Agency (NSA) have issued an Alert (AA20-205A) to urge all National Security Systems (NSS), Department of Defense (DoD), Defense Industrial Base (DIB), and other U.S critical infrastructure to take immediate action to secure their OT assets.

In this article, we will detail 4 guide to strong OT security. If your organization needs a strong OT security, then read on.

Cyber Kill Chain use areas

How Cyber Kill Chain Can Be Useful for a SOC Team? (Part 2)

Installation: At this stage, SOC analysts are advised to deploy a Security Information and Event Management (SIEM) and Host-Based Intrusion Detection System (HIDS) to detect attacks. To deny an attack, Cyber Kill Chain recommends using Two-Factor authentication, strong password, and privilege separation as well as disrupting attack using data execution prevention. If the attackers successfully penetrate corporate critical IT infrastructure, SOC teams must contain them in a timely fashion to mitigate damages. To this end, Cyber Kill Chain recommends employing Inter-Zone Network Intrusion Detection System, App-aware firewall, and trust zones.

How Cyber Kill Chain Can Be Useful for a SOC Team? (Part 1)


The world is being digitalized more and more. The technological advancements both in terms of hardware and software are grabbing the attention of cyber criminals towards enterprises of each size (e.g., small, medium, and large). The attackers use a complete chain or number of stages to launch a cyber-attack. A Cyber Kill Chain defines all these potential stages and the SOC team can use them to identify, detect, prevent, and contain attack before it causes real damage to the organization.

In this article, we will explore what is a Cyber Kill Chain and how is it useful for a SOC team.

The most famous buffer overflow attacks

Buffer Overflow Attack Prevention


Buffers are regions of memory storage that temporarily store data while it’s being transferred from one location to another. A buffer overflow, also known as a buffer overrun, takes place when the volume of data is more than the storage capacity of the memory buffer. Resultantly, the program that tries to write the data to the buffer replaces the adjacent memory locations. If a user enters 10 bytes, that is 2 bytes more than the buffer capacity, the buffer overflow occurs. This problem generates a security breach in the system. For example, log-in credentials take 8 bytes in the memory buffer to write username and password.

Access management in IT

Role of Identity and Access Management in Cybersecurity


In IT security debates, projects aimed at managing access and identifying users are considered fundamental. However, the processes and technologies for controlling permissions have proved challenging. To solve this dilemma, what is now called Identity Access Management (IAM) was created, which involves the definition and execution of identification processes related to the most critical businesses for a company. For example, e-banking companies implement strict rules to verify identities before allowing them access to their websites.

In this article, we will examine how IAM helps and why it is important today.

The Consequences Of Problematic Access Management

When we do not have access control, it is practically impossible to guarantee that features are used only by their target users. If a problem occurs, the person responsible for the system is unable to track the person responsible for it. The lack of permission management allows users to have access to services not needed by them, making room for improper access and possible application failures. This may result in data breaches that cost millions of dollars and reputational damage.
