Defense-in-Depth: A Layered Approach for Modern Cybersecurity

 

The cybersecurity landscape has shifted dramatically in recent years. Malware, phishing attempts, and data breaches have grown in frequency and scope, prompting organisations to invest more time and money into enhancing their cybersecurity strategies. Organisations should be aware of the shifting threat landscape, asking themselves what issues they face today and what specific steps they can take to mitigate the risks of cybercrime

This was the topic of discussion between cybersecurity expert Jon Bernstein and John Shier, field CTO commercial at Sophos, as they analysed how the security landscape is moving with increasingly sophisticated crime and what this implies for the future of business security. 

Shier highlighted multiple critical takeaways, including the evolution of cybercrime professionalisation and specialisation. Firewalls and multilayering defences, such as multi-factor authentication (MFA), have become critical additions to current organisational security layers in order to react to changing hacker techniques.

“We are getting better at detection, and are able to catch these people in the act sooner, but they know that. They know we’re better at detection, we have better tools and services, to aid in this quest of detecting them sooner and so they move faster, naturally,” noted Shier. “The faster we attack, the more we start to prevent these attacks, then the faster we can break their cadence and get in the way.” 

Shier also reviewed Sophos' recent research, 'Stopping Active Adversaries,' which identifies the most prevalent and emerging ways hackers infiltrate organisations. The study, which is based on an evaluation of 232 large cyber incidents managed by Sophos X-Ops incident responders, provides helpful suggestions for security strategy. 

Among its primary results are that compromised credentials and exploited vulnerabilities remain the most common entry points, and attacks are becoming faster. Ransomware dwell duration was reduced to five days in 2023, down from larger levels in previous years, and 91% of ransomware assaults occurred outside of business hours, highlighting the necessity for organisations to invest in round-the-clock protection.

Three steps to enhance security 

Shier highlights the need of three elements for organisations in combating these threats: security, monitoring, and response. "Securing means increasing friction wherever possible, using strong levels of multifactor authentication. "That is critical, and it should be applied wherever possible," Shier added. 

Shier warns that cybercriminals will only adapt when absolutely necessary. He suggests raising the bar so high that some cybercriminals' tactics "won't be worth it anymore," but reminds businesses that they no longer need to navigate their cybersecurity journey alone, and can rely on beneficial partnerships to maintain airtight security for their organisation and employees.

“Getting security right can be difficult and time-consuming, it’s resource-consuming and expensive,” Shier added. “When you find yourself in a situation where you think, I’m having trouble doing this on my own, go ask for help. There are plenty of organisations out there, whether it’s people you can partner with for your IT infrastructure or vendors that can help you, ask for help, we’re here to help, and we’ve got the experience to keep you safe.” 

During this extensive discussion, Shier offere more insightful details and recommendations to help organisations create a thorough cybersecurity plan. The dynamic landscape of cybercrime and security underscores the significance of implementing multi-layered defences and the necessity for constant protection. Businesses can keep their digital assets safe and remain ahead of cyber threats by taking proactive measures to secure, monitor, and respond.

What Will be The Biggest Cybersecurity Threats in 2023?

 


With the advent of the digital revolution, corporations, organizations, and even government entities are increasingly relying on computerized systems to run their day-to-day operations, and as a result, cybersecurity has become a necessity to protect data against numerous online attacks and unauthorized access. As technology continues to advance, cybersecurity trends are changing at a similar pace. News about data breaches, ransomware, hacks, and other threats has become the norm as technology continues to develop. 

As we look ahead to 2023, cybersecurity continues to be one of the top concerns for chief information officers. It has been estimated that there were 2.8 billion worldwide malware attacks and 236.1 million worldwide ransomware attacks in the first half of 2022. According to the data, six billion phishing attacks are expected to have been launched around the world by the end of 2022. 

In the year 2023, it is expected that IT will have to contend with these eight top security threats as these are the most significant cybersecurity trends. 

Top 8 Security Threats For Next Year 

1. Malware 

A malware program is a malicious piece of software that is planted on a network or system. This is done to cause damage to the computer, server, workstation, or network it is installed on. Malware can extract confidential information, deny service and gain access to systems. 

It is the responsibility of IT departments to monitor and stop malware before it enters a network or system by using security software and firewalls. The bad actors behind malware continue to use new methods of evading detection as they develop new ways of doing so. As a result, it is essential to keep current security software and firewalls up-to-date to prevent security threats. 

2. Ransomware 

There are several different types of malware, but ransomware is the most popular. It is capable of preventing access to a system or threatening to leak proprietary information as a result of its actions. To unlock systems or retrieve information that has been encrypted as part of ransomware, hackers demand that their victims pay them a cash ransom. 

Currently, the number of ransomware attacks being carried out against companies in 2022 is higher by 33 percent than it was in 2021. The majority of companies pay ransoms to regain access to their systems. However, they are attacked once again by the same cyber criminals who were behind the ransomware attack earlier. 

Often, ransomware can gain entry into an organization's network through connections with vendors and suppliers whose network security is lacking. 

A secure supply chain starts with the security measures that are used by suppliers and vendors. This is so that business owners and suppliers can be assured that the supply chain from start to finish is secure from beginning to end.

 3. Phishing 

The majority of us have encountered suspicious emails at some point or another. This is often the case, or perhaps even more alarmingly, emails that appear to be legitimate and from a trusted source but are not. Phishing is the practice of sending emails in an attempt to trick you into opening them. 

Phishing is one of the biggest threats companies face today. This is because, as a result of the ease of opening bogus emails, it is easy for unsuspecting employees to spread viruses. In the workplace, training employees on how to recognize phony emails, report them to the company, and never open them can make a difference. To ensure that the best email habits are being taught, IT should work closely with HR to achieve this. 

4. IoT 

It is estimated that 61% of businesses in 2020 will use the Internet of Things, and this number is only growing. Security risks also grow as IoT grows, which is a consequence of the expansion of IoT. There is a well-established reputation among IoT vendors for the lack of security that is implemented on their devices. It should ensure that IoT vendors are checked for safety as part of the RFP process to combat this threat. In addition to this, IT is also able to reset the IoT security for devices so that they comply with corporate standards when it comes to security 

5. Multi-layer security 

What is the right amount of security? You need to know that if your network has been firewalled, security monitoring and interception software are installed, servers have been secured, multi-factor identification sign-on has been issued to employees, and data encryption has been implemented. Still, you could have forgotten to lock physical facilities that contain servers or to install the latest security updates on your smartphone. 

Several layers of security must be managed and monitored by IT to ensure the safety of the network. Creating a checklist for every stage of the workflow that may be a potential security breach point can be a good way for IT to enhance security.
