When it comes to cyber security, no organization  can  be too careful  as cybercriminals actors are constantly crafting new ways to hack  networks. To effectively guard against them  enterprises should focus on mitigating all known gaps in their network security posture.

Of the most notable vulnerabilities is the zero-day exploit. If an organization already has this, they have a big problem that they must prioritize eliminating it as quickly as possible. Even top tech companies have encountered  zero-day bugs in their network. The prevalence of software programming errors leaves  cracks for hackers to locate unintentional flaws which they use for zero-day cyber-attacks.

However, one reassuring fact is that zero-day is a household name in cybersecurity, and fortunately, software programs exist to continuously protect against such malicious attacks.

So what are zero-day exploits?

Zero-Day Attacks

The term ‘zero-day’ is a broad concept that describes an unknown vulnerability discovered and exploited by hackers  in a company’s network.  Cyber criminals inevitably  target and exploit these weaknesses when they discover them. Due to the lack of defense mechanisms in place, these attacks can amount to quick lucrative profits for cybercriminals, and devastating losses for organizations.

As the name indicates, “zero-day” references any vulnerability that a developer or vendor just learned about  and consequently have zero days to fix with updated software patches. However, the consequence of leaving it unattended is a chance to exploit the vulnerabilities.

How it Works

There are three main ways to view a zero-day:

• Zero-day vulnerability: These involve an easily exploited software weakness that hackers discover before the developer does.
• Zero-day exploit: These refer to the methods threat actors use to gain access to a system through a discovered zero-day vulnerability.
• Zero-day attack: Cyber actors use the zero-day exploit to access the system, steal data, or cause damage to an organization.

When bad actors identify vulnerabilities before the developers, they create an exploit code. Through this code, victimizing users becomes a walkover. They utilize socially engineered email to access vulnerable systems. Once the user visits a website with malicious content, it downloads malware.

The malware can also infiltrate files, steals data or identity, and perform other crimes. In some cases, once they infiltrate a network, some immediately act on it. However, others wait for the most valuable time to strike.

How to Identify Zero-Day Attacks

The traits of zero-day attacks are already the stuff of nightmares, though correctly identifying them is a whole other beast to deal with. They are challenging to detect with traditional cybersecurity approaches. Moreover, their associated vulnerabilities can come in various forms such as bugs, broken algorithms, password security issues, and more. Hence the use of advanced detection and patching practices.  

An organization might see the following signs when attacked with a zero-day exploit:

• Unexpected Legitimate Traffic: When a company receives unexpected legitimate traffic, it can be a red flag. At this point, an emergency upgrade on all systems becomes expedient. Also, it is crucial to identify where the traffic is coming from and configure all applications as preventive measures.
• Scanning Activity From a Compromised Server or Client: Scanning activities emerging from a client or a server require prompt action. Such occurrences call for analyzing the event with the aid of the affected vendor to provide a better understanding of the situation. As tricky as detection may be, there are always ways to suspect a zero-day exploit. Here are some ways to detect previously unknown software vulnerabilities:
• Monitoring via Statistics: Some anti-malware vendors provide statistics on previously detected exploits. This data provides helpful insight into a machine learning system that identifies contemporaneous attacks. Despite this, organizations need not throw caution to the wind as the detection method still has its limitations.
• Behavior-Based Monitoring: The procedure serves to create alerts as it picks out suspicious traffic and scanning on a network. For most malicious software, probing a system is a mode of operation. So instead of analyzing signature activities, the detector observes malware interaction with the device.
• Detection Based on Signature Variant: Zero-day exploits often come with digital signatures. These signatures get fed into artificial intelligence systems and machine learning algorithms.  This action identify the variants of previous attacks.
• Hybrid Method of Detection: The name says it all. This method focuses on the combination of all three approaches for effectiveness.

How to Protect your Enterprise from Zero-Day Exploit

Prevention is a far more effective approach than remediation. Organizations that focus more on keeping attackers and hackers away tend to save themselves from significant damage. However, as the threat increases, it becomes necessary to put procedures in place to prevent such malicious activities. There are several ways to prevent or eliminate zero-day exploits.

Below are some helpful tips to get organizations started:

Software Patch Management

One way to avoid a zero-day exploit is to immediately install software patches at the detection of a new vulnerability. Of course, there’s no guarantee of it preventing an attack, though it makes reducing the risk of attacks  an easier task.

Furthermore, three factors exist in delaying the use of security patches. First is the discovery of vulnerabilities. Most software vendors need time to discover the vulnerabilities. Upon the discovery, developing a patch becomes the next phase before it is then distributed to users.

Scanning for Vulnerabilities

Vulnerability scanning quickly helps to discover zero-day exploits where vendors create a form of simulation attack on software codes. Other procedures include a review of the codes and finding new vulnerabilities.

This method also does not guarantee the detection of all zero-day attacks. Enterprises need to perform code reviews, sanitize them, and act on the result of every scan. These actions require promptness, as cybercriminals are constantly on the prowl.

Use Multilayered Protection

Multilayered malware protection can go a long way in protecting against zero-day exploits. As an enterprise, consider using behavior monitoring protection as a function. Also, explore sandboxing, hashing, and threat intelligence. What these helps to achieve is to prevent the downloading of malware despite a connection with a cyber actor.

Most enterprises should consider collaborations with Advanced Threat Detection and Response companies. Other procedures by these companies include the use of powerful correlation engines that produce findings with near-zero false positives while offering automatic and manual remediation.

Deployment of Web Applications

Web applications provide amazing preventions against zero-day attacks on the network edge. One of the most effective applications to consider is the Web Application Firewall (WAF) which filters and monitors HTTP traffic between the internet and the web application.

Most WAF protocols come in a seven-layered defense. However, there’s no design against all forms of attacks. As part of a suite of tools, it creates a comprehensive defense against several attackers.

WAF’s design helps review incoming traffic and filter malicious content targeting security vulnerabilities.

Another application to consider includes Runtime Application Self-Protection (RASP). RASP operates by sitting inside an application and examining request payloads.

Educate Everyone

Since threat actors often capitalize on human error, one way to prevent a zero-day exploit in your organization is to educate everyone on. Therefore, users and employees must be well aware of good security and safety habits to ensure the safety of networks and users.

Preventing the Spread

Professionals and experts must realize that most preventive procedures offer excellent first-level protection. However, many of these efforts have limitations in protecting against zero-day attacks.

A permanent solution for zero-day exploits remains challenging for even the most vigilant systems executives. When an enterprise discovers an attack, preventing a spread will reduce the extent of the damage. Organizations that limit connections to the business require better control and management of various threat scenarios. They can then mitigate the spread of the exploit within the organization after the initial infection.

Final Thoughts

Protecting an enterprise against zero-day attacks, exploits, and vulnerabilities is crucial to the integrity of its data. Proper procedures and safeguards significantly reduce the risks to critical data and systems. No organization can ever go wrong with an adequate detection, mitigation, and prevention strategy.

Organizations handle cybersecurity issues from varying perspectives. It is the precise reason they apply different strategies for fulfilling security objectives. The goal notwithstanding, one essential element to consider is combating the compounding surge in vulnerabilities. While fixing all may look like a ‘wild goose chase,’ adopting a sustainable approach is the way to go.

At the moment, top managers of companies are more focused on cyber risk than severity levels for security issues. However, the topic encapsulates all potential business losses – financial, operational, reputation, regulatory, and more. Therefore, it becomes necessary to stress that cyber risks are business risks…hence the shift to risk-based security models.

Analyzing Vulnerabilities, Threats, & Risks

In today’s world, data and its protection involve three critical factors for any business. Customers need security guarantees for their personal information. Every organization needs to focus on the issues bordering on cyber security threats, vulnerabilities, and risks. Therefore, it becomes expedient to understand how the three components intertwine fully. The information helps to give a firm grasp on data security issues, along with a focus on the appropriate area for full-service delivery.

• Threat: Focuses on a new incident with the potential to harm a system or the entire organization. It could take any of these three forms; natural, intentional, or unintentional. Cybercriminals constantly devise new and creative ways to compromise data. When organizations take measures to assess threats regularly, they become well prepared for them.
• Vulnerability: Refers to a known weakness of a resource prone to exploitation by cybercriminals. An understanding of this crucial aspect is the first step to managing risks. You can begin with vulnerability testing. It is a great way to ensure the constant security of a company’s system. When the weak point gets identified, developing a strategy becomes easy.
• Risk: Refers to losing the integrity, availability, or confidentiality of data or information systems when a vulnerability is exploited. It often results in an adverse impact on the operations and assets of an organization.

Cybersecurity risks come in various forms and can evolve at an alarming pace. It is the reason why risk management has become a never-ending responsibility. The goal is to prevent financial or reputational damage in a data breach or cyber-attack.

Risk-Based Security: A Safety & Soundness Process

Data is always the primary target for most cyber actors, and it’s an arduous task to defend against every threat. Over the years, organizations focused their resources and budget on security technologies like anti-virus, firewalls,SIEMs, and more. They have become more concerned with detecting and preventing security incidents.

Subsequently, the level of complexity and the increased threat of mobile and IoT devices have made this focus obsolete. The current level of risk is too high, and it is vital for top management to focus on risk reduction through data analysis and rapid incident response.

A risk-based security approach covers five key elements:

I. Attack Surface Visibility & Context

An attack surface is a collection of all attacker-exposed assets. It covers all resources in areas like the cloud, third-party environments, or the company’s subsidiaries.

One critical security issue is being unaware of the exact location of an organization’s assets or digital infrastructure. As a result, some companies cannot tell whether these assets are fully protected. It is a phenomenon called a shadow risk. The implication is that unmanaged assets become easy access points for attackers. Therefore, organizations must expose all shadow risks by assessing and mapping their attack surface.

The truth is this; you can’t protect what you don’t see. So it’s time to make your data work harder. One effective way to carry this out is through attack surface analysis and management. As a universally recognized approach, it is the foundational step necessary for guiding resource investments and security programs. Moreover, organizations need to implement a context-aware change management approach. That way, there can be a balance for rapid changes in all infrastructure and supporting infrastructure.

II. Breach and Attack Simulation

A breach and attack simulation is an advanced computer security testing method. You may call it the “hack-yourself” approach. However, security is never static, so you stay on top of the ever-changing trends.

Attack simulations identify vulnerabilities by mimicking cyber actors’ plausible techniques and attack paths. The approach provides a continuous, automated penetration test. It also improves the previous limitations of red and blue team testing.

This technology tracks and resolves vulnerabilities, and also gives regular updates and alerts on imminent risks to your network. It also runs on a 24/7 basis and gives organizations deeper visibility of their defense-readiness level.

III. Cybersecurity Risk Scoring

A cyber risk score focuses on the evaluation of a security posture. It aims to convert these evaluations into a simplified, comprehensive risk score. The concept of security posture helps organizations know the level of asset safety they possess. That way, they know the area to focus on for improvements .

An organization that takes such concrete steps shows they are meeting its cybersecurity obligations. In another sense, it leads to increased revenue generation. The reason is that customers and partners view security as a competitive differentiator. Scoring has therefore become an essential aspect.

IV. Cyber Exposure Management

Cyber exposure management helps organizations identify, predict, and take action against risks. The discipline hinges on risk-based vulnerability management. That way, you continuously assess your system’s security posture and health. Additionally, organizations also get to unify business objectives with security goals.

V. Vulnerability Assessments

A vulnerability assessment involves a review of security weaknesses in a system. It evaluates how susceptible a system is and assigns severity levels. There’s also the aspect of recommending remediation or mitigation.

Some of these vulnerability assessments include:

• Host Assessment: Host assessments focus on the vulnerability of critical servers to attacks.
• Database Assessment: These involve the assessment of a database for misconfiguration and vulnerability. It also entails classifying sensitive data on a network.
• Network Assessment: Network assessments involve the assessment of policies and practices as a way to prevent unauthorized access to resources.
• Application Scan: These use automated scans to identify security vulnerabilities in web applications and their source code.

Risk-Based Security & Risk Reduction

Organizations need to recognize that breaches are inevitable. However, we also see that attackers have become better at what they do than the defenders. Therefore, there’s an urgent need to modify the current paradigm of cyber security towards risk-reduction through risk-based security models.

Where to Start?

• Assess the status of critical control systems and operations for security vulnerabilities that need addressing.
• Revisit security and alarm management standards. This requires significant coordination between all players in the system.
• Develop cross-collaboration between engineers and network administrators

Your employees can use their laptops or mobile devices from anywhere within your corporate building to access your WiFi network. Convenience is often coupled with risk however, and many WiFi networks these days simply do not have the appropriate security measures needed, making them susceptible to cyber threats that put your company’s data and customer information at risk.

However, you can protect your network and sensitive data by using some of these best practices for WiFi network security. We’ll focus on the four most effective methods for WiFi security:

4 Best Practices for Enterprise WiFi Security

When it comes to WiFi security and preventing unauthorized access and data loss, businesses must take the time to thoroughly plan out a comprehensive strategy. Although the degree of protection needed, and the available budget determine the final security measures, the essential guidelines listed below can be helpful for getting started.

I. Maintain User Segregation Between Internal and Guest Users

When guests come to your place of business, they will most likely want access to your WiFi network. While giving this to your customers seems a perk, you must maintain a barrier between their access and that of your employees. If they do not need access to any company’s resources, it is beneficial to your company’s safety to ensure that they are kept separate.

II. Carefully Select Your SSID Name

Your SSID shouldn’t advertise your company. Organizations often expose their networks to attackers, and in densely inhabited areas the risks of a hack are much higher. Even with an unassuming SSID, hackers may locate your WiFi network. Yet, having a safename increases the difficulty of hacking a network. Note that banal SSIDs assist WiFi security but aren’t a must-have.

III. Utilize Intrusion Prevention Systems for WiFi Networks

Include a wireless intrusion prevention system (IPS) inside your Wi-Fi security to protect your system. These devices monitor and detect targeted WLAN cyberattacks that utilize packet floods,ARP (Address Resolution Protocol),spoofing, and malicious broadcasts.

Snort refers to a network intrusion prevention system that can swiftly detect and handle potential threats. as a preemptive approach to securing your network. As with intrusion detection, these systems also help monitor network traffic. Depending on your network administrator’s security controls, they can rapidly respond against a prospective exploit.

IV. Mobile Device Management (MDM)

Mobile device management (MDM) allows you isolate and manage access for numerous mobile devices which protects your corporate network and data in numerous ways, including:

• Monitoring regulatory compliance activities.
• Remotely deactivate or disconnect illegal users and their devices.
• Centralize device update auditing.
• Protect mobile devices with your company’s security protocols.
