Benefits of Performing Code Reviews | Nettitude

Posted by Nettitude on Feb 28, 2023


When performing a penetration test, most companies focus on traditional methods with limited knowledge about the targeted system. In fact, if you are dealing with software or programming at a deeper level, there may be threats or vulnerabilities in the code that your team is not aware of. This is where a code review as a service comes in.

In essence, a code review is where every part of a program’s code is analysed to make sure there are no risks of vulnerability that someone else can take advantage of. It also ensures that any confidential information is hidden, which is a vital aspect of cybersecurity. 

Let’s take a closer look at the benefits of a code review as a service.

PCI DSS v4.0 and SAQ A | Nettitude

Posted by Nettitude on Jan 31, 2023


Many organisations accepting card payments see SAQ A as the target operating model, as this has the most effect on reducing the PCI DSS requirements with which an organisation must comply. It does not come without risks though, as the third-party service providers you have engaged with must always maintain their compliance to support yours.

So, what remains the same, and what has changed with the arrival of PCI DSS v4.0? The first blog of this series explained the core format changes for all the SAQs, here we turn to the specifics around SAQ A.

SAQs and the impact of PCI DSS v4.0 | Nettitude

Posted by Nettitude on Jan 16, 2023


The PCI Security Standards Council (SSC) published PCI DSS v4.0 on the 31st March 2022. The combined efforts by the SSC, payments brands, participating agents, and QSA the community have yielded a significant overhaul that promises to provide a framework for securing payment card information in the future.

There has since been a lot of activity surrounding the release, which gives rise to a problem. With such an overhaul, people are suffering from information overload and are unable to find a starting point for their organisations. Nettitude will break down what the changes mean and what a merchant or service provider needs to migrate, starting with a series of blogs discussing changes to self-assessment questionnaires allowing you to quickly start forming your plan to move to PCI DSS v4.0.

Digital Footprint and Why it Matters to Your Organisation | Nettitude

Posted by Nettitude on Dec 31, 2022


Virtually every modern organisation relies on the internet and connected devices to communicate with customers, operate internal processes, and deliver its services. However, the digital remnants left behind from these activities – known as your digital footprint – can give hackers and malicious users the information they need to compromise your operations. 

So, what can you do to protect yourself? An expert team like Nettitude can assess these ‘electronic breadcrumbs’ to identify exposed business-critical information and safeguard it against cyber threats. Here, we explore how organisations must limit the information shared online while explaining how it can be used against them.

An Introduction to Zero-Click Attacks | Nettitude

Posted by Nettitude on Dec 30, 2022


Cybersecurity is a constant battle as there are always new threats to consider and safeguard against. With companies and individuals storing an incredible amount of personal and business data on their devices, keeping this information protected requires rigid security practices.

However, one of the most challenging cyber threats to prevent is zero-click attacks. These are especially dangerous because, unlike more common cyberattacks, a victim’s devices can be compromised without them ever knowing. So, what can be done? 

Here, we explore how to recognise these malicious malware attacks while offering tips that help prevent your devices from being exploited.

Security Considerations in AWS | Nettitude

Security Considerations in Amazon Web Services (AWS)

What is Amazon S3?
What is Amazon EC2?
Misconfigurations in AWS EC2
AWS Identity and Access Management (IAM)
What is Amazon RDS?

There are several reasons to adopt cloud services, and there has been a growing increase in total spend on cloud services over the last decade. Cloud computing offers speed and agility, competitive pricing models to deploy various IT resources and flexibility.

The cloud services market share is dominated by Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Of the three main providers, AWS currently occupies the highest percentage of the market as of 2022. This blog focuses on security within AWS specifically, highlighting security issues within common services as well as secure design choices and practices.

AWS has hundreds of services within its global infrastructure. These can be broken down into high-level services such as Storage, Compute, Databases, and Security, Identity & Compliance. Below are some examples of the most popular services that sit within these class types:

● Storage – Simple Storage Service (S3)
● Compute – Elastic Compute Cloud (EC2)
● Security, Identity & Compliance – Identity Access Management (IAM)
● Databases – Relational Database Service (RDS)

Building Baseline Security in the Cloud | Nettitude

Building Baseline Security in the Cloud with Policies

AWS (Amazon Web Services) policies
Microsoft Azure policies
How implementing baseline policies in a cloud environment helps

Cloud security can often feel like an overwhelming practice. Cloud environments can employ many resources with varied functions, leading to the complicated task of securing these resources. Implementing baseline policies within your cloud environment can simplify the task of implementing common security practices uniformly across all resources. Cloud providers simplify this practice through policy-checking services. In Amazon Web Services (AWS), the service is called Config, while in Azure the service is called Policy.

Within AWS Config and Azure Policy, there are policy deployments in line with the Center for Internet Security (CIS) recommendations. The CIS issues a document with configuration recommendations for common services within cloud deployments. These services include identity management, compute, storage, networking, monitoring, and database configurations. For AWS, the list of recommendations is approximately 60 items. Instead of examining each item within a document, using AWS Config or Azure Policy can automate the process and alert you to many misconfigurations within minutes. This offers quick and easy deployment of baseline security configurations and continuous monitoring of the compliance state of those policies within the environment.

The following sections detail how to implement these baseline policies for AWS and Azure. It should be noted that some costs may be incurred related to the use of these services.

What is Pretexting in Cybersecurity? | Nettitude

Posted by Nettitude on Oct 31, 2022


A pretext is designed to convince a target to divulge information to an attacker. This information could include, but is not limited to, requests for company documents, user credentials, and personally identifiable information. A successful pretext convinces the target that a request is legitimate and the information being asked for is reasonable.

How to Prevent Ransomware & Protect Your Business | Nettitude

Posted by Nettitude on Sep 22, 2022


When a ransomware attack hits, time is of the essence to limit the impact on your organisation's operations. It has been said that prior preparation and planning prevents poor performance, helping with time management and ensuring that tasks are completed most efficiently.

The threat from ransomware continues to develop significantly. Previously, one or two endpoints would be compromised and have ransomware deployed to them. Now, attackers are compromising entire networks and deploying ransomware to every endpoint within the network.
