Essential Business Cyber Security Advice for Businesses

The core cyber security tips that keep your business safe

The solution is quite simple: awareness training for all staff is a crucial tactic to aid your security and stop hackers succeeding with their phishing campaigns. Look at it like this, if a new employee has no knowledge of phishing or social engineering, how likely are they to succumb to the demands of a hacker posing as their CEO requesting to purchase a gift card on their behalf or click on a suspicious link? As a result, this could lead to an employee revealing sensitive information which can be exploited for financial gain.

Consider what would happen if that same employee was trained and aware of the primary strategies used by hackers and the results of yielding to such demands from unrealistic internal requests. Training should not be underestimated or overlooked, and organisations should seek to invest in continual security training to strengthen their cyber resilience.

Changing default credentials is a necessity

If businesses are serious about protecting their data and personal information, then changing default credentials is a no-brainer, right? Default credentials are assigned by developers or manufacturers to allow access to software or hardware devices during initial setup. So, when these credentials are not changed, it is generally due to complacency or ignorance by IT admins. Time and resources are also factors for IT admins to ignore changing default passwords.

Even the most novice of hackers will understand that the path of least resistance is the one most likely to be successful for an attack. Default credentials can be easily accessed over the internet, therefore businesses could be leaving themselves open to opportunistic attacks. Common devices and systems which can use default credentials include:

• Wi-Fi routers

• Laptops

• Smartphones

• Printers

• IoT devices

From observing our honeypot data, it is clear hackers are using default credentials as a means of carrying out brute-force attacks. For example, our cyber security research showed multiple brute-force attempts using default Raspberry Pi credentials. We know that hackers would not use these methods if they were not successful or so easily available on the internet, so this indicates a trend of poor password management. Failing to change default credentials is a rookie mistake and one which can lead to hackers infiltrating servers to plant malware, manipulating networks and devices, and stealing sensitive data once they have access.

Data from report shows passwords like ‘<No Pass>’, ‘admin’ and ‘PASswoRD’ were the top 3 credentials used to attempt to infiltrate our honeypot servers. Generic passwords like these are enticing for hackers and unlikely to thwart them from breaching systems. However, passwords which are unique, memorable, and avoid using personal information such as names or destinations will be harder for hackers to guess. Adding multi-factor authentication (MFA) will also add an additional layer of protection to secure your business. To secure your business it is imperative to change default credentials to prevent hackers from easily breaching your systems and accessing company and personal information.

Managing risk with timely patching

Patching should be a key component of a business’ security plan. Keeping operating systems and software up to date is one of the best ways to safeguard your network against security breaches. However, upgrade costs, system downtime, compatibility issues and a lack of resources are all major factors in why patching can get ignored. It can also be time-consuming, so businesses with under-resourced IT teams will fall short of deploying patches quickly and consistently. For example, outdated libraries and components ranked in our top vulnerabilities found during penetration testing. When businesses don’t patch, they effectively leave the door wide open for hackers to exploit vulnerable systems.

It’s worth mentioning that patching alone won’t secure businesses against every cyber security threat. The Log4j vulnerability which came to light at the end of 2021 was an example of this. Organisations were instructed by CISA to immediately “assume compromise and to update or isolate affected assets” whilst hunting for malicious activity. Cyber security vendors were also instructed to inform end-users of products which may include the vulnerability and to update software as a priority. However, the initial release of patches did not fully address all discovered issues in Log4j, leaving applications exposed and not completely protected against vulnerability. Moving quickly to fix unpatched systems is important to prevent the different types of hackers from attacking weakened systems and exploits like Log4j vulnerability.

A well-executed patch management policy focusing on scheduling, prioritisation, testing, deployment, monitoring and reporting can help businesses maintain a regular patching process and ensure that it doesn’t get neglected. Nevertheless, even with a patch management policy in place, unless organisations have a dedicated security team to manage patching correctly and efficiently, businesses will continue to be at risk of cyber-attacks. To ensure the security of your business, it is crucial that updates don’t fall through the cracks and patching is executed in a timely manner.

Importance of compliance

Maintaining compliance is important in order to meet baseline security standards. GDPR, Cyber Essentials, ISO 27001, PCI DSS… the list goes on, but each regulation and legislation is in place to serve a purpose – to help protect the data of businesses, their customers and their supply chain. When delivered correctly, compliance can also help a business differentiate from their competition, develop brand awareness and increase customer trust by demonstrating a commitment to security best practice.

The complexity and lack of understanding of compliance proves to be a hurdle for many businesses. Changes in compliance can prove challenging to organisations who lack the expertise or guidance on how to stay ISO compliant. In 2021, businesses failing to implement the ISO 27001 standard was simply because of a lack of understanding of what it is. ISO 27001 is beneficial not just for your business but for the security of your supply chain as it demonstrates your business is working to the highest security standards. However, changes in policies and standards are also needed to reflect the ever-evolving business landscape. This was one of the main drivers for new changes being introduced to ISO 27001 and Cyber Essentials certification.

We understand the difficulties that businesses can face in achieving certification and compliance. To combat this, seeking guidance and accruing knowledge on the importance of compliance and how it can help secure your business can help break down these barriers and ensure you are equipped to achieve compliance with confidence. To secure your business and remain compliant, it is also necessary to adopt a culture where compliance plays an integral part of your risk management and cyber resilience strategy.

Cyber threats will continue to evolve but also present businesses with many of the existing threats we’ve encountered in previous years. Understanding your evolving threat landscape and addressing existing gaps in your cyber security strategy will help to strengthen your cyber resilience. So, here are some key actions for you to consider to secure your business and minimise the threat of a cyber-attack:

• Invest in cyber security training. Cyber security training can boost your workforce’s awareness of the most common cyber threats to help secure your business as your first line of defence.

• Ensure default passwords are changed when installing and introducing new software or devices into the business. A strong password policy is crucial to the security of data while additional layers of security are recommended to secure your business and personal information.

• Secure your business by updating operating systems and software as soon as new patches become available. Patching is important and will be key to preventing hackers.

• Make sure you are compliance ready for 2022 amidst changes to Cyber Essentials and ISO 27001. Additionally, understanding the importance of compliance and keeping up to date with changes will help secure your business from security breaches which result in fines and reputational damage.
