How IPS Security Strengthens Cyber Defense Strategies

cyber security

An IPS security solution detects and blocks malicious traffic before it can reach its targets. Unlike IDS, which only detects threats and notifies IT and security teams, IPS shuts down attacks, preventing sensitive data compromise. IPS solutions can use either signature-based or anomaly-based detection to identify malicious activity. They then take automated actions based on configured policies to protect enterprise systems.

Adaptive Detection

As cyberattacks become more sophisticated, defense strategies must evolve to prevent them. A robust Defense-in-Depth architecture is a crucial component. It must include physical security measures like biometrics and IoT-enabled security systems, network security including adaptive detection technologies, and endpoint protection solutions like antivirus software. Traditional security services are no longer enough to defend against the most sophisticated threats. Today’s agile business environment exposes organizations to high-impact threats daily, leading to lost revenue and damaged reputations. Waiting to respond to these incidents after they occur could be more efficient and can result in costly delays and disruptions. Adaptive security technology enables enterprises to assess risks and deliver proportional enforcement continuously. It analyzes behaviors, events, and the characteristics of users, systems, and cybercriminals. Then, it uses this knowledge to predict cyberattacks and any discrepancies in activity. IPS security incorporates active defense techniques that outwit hackers and make it harder for them to advance through the business networks. For example, device decoys and digital baiting obfuscate the attack surface by wasting attackers’ time and processing power. These tactics also reduce the number of entry points hackers can use to infiltrate the systems. This prevents them from obtaining the information they need to carry out their attacks.

Virtual Patch

Virtual patching is a robust breach-prevention practice that strengthens an organization’s defenses against threats that exploit known vulnerabilities. The process involves rolling out security policies that block the network paths to and from the vulnerable asset to prevent and intercept attacks without modifying the application’s code or diverting traffic to infrastructures that can’t support surges. The best virtual patches are based on real vulnerabilities identified via penetration testing or scanning and prioritized by the organization’s vulnerability management solution. This approach reduces the risk of a gap between when the security team identifies vulnerable assets and when official vendor patches are applied, eliminates the need to deploy workarounds or emergency patches, extends the patching cycle, and minimizes the impact on business productivity. The best virtual patching solutions are multilayered, enabling them to inspect and analyze an application’s data packets, traffic, behavior, and environment to adapt to different circumstances. These systems may be implemented on the cloud or physical, virtual, or hybrid infrastructures. They can also identify the specific components and environment settings of the applications they protect. For example, the most effective system has an endpoint WAF that recognizes the application and its environment to adjust the firewall more efficiently, reducing the number of policy enforcement points needed.

Inline Deep Learning

Inline deep learning is the application of ML technologies to analyze and detect malicious traffic as it enters a network, blocking threats in real-time. It reduces the time between visibility and prevention from days to seconds, making it a key component of effective cybersecurity strategies. ML algorithms can process massive amounts of data, making them ideal for detecting and interpreting cyber threats. They can detect patterns, trends, and anomalies that human analysts miss. This is possible thanks to how neural networks mimic the brain’s functionality and learn from large datasets. Malware detection is an everyday use case for ML, with models able to analyze file characteristics and behavior to pinpoint malicious activity. Other ML-based capabilities include predicting the likelihood of an attack, prioritizing vulnerabilities, and assessing their severity. While ML is an essential technology for cyber defense, it requires substantial computing power and resources to operate. Moreover, its results must be more immediate and accurate to impact threat detection and response times significantly.
With attacks on businesses and critical infrastructure growing in complexity, frequency, and scope, companies must adopt new tactics to keep pace. Organizations increasingly turn to AI-based cybersecurity to better protect operations and prevent costly breaches.

Real-time Deep Packet Inspection

Deep packet inspection is one of the core technologies incorporated into firewalls. It identifies risky traffic and blocks suspected assaults in real-time. Often called “pattern or signature matching,” it examines each data packet against a database of known attacks and looks for malicious code patterns. While effective against buffer overflows, denial-of-service attacks, and some forms of malware, this approach doesn’t protect against zero-day vulnerabilities or new threats. While stateful packet inspection merely assesses information in a packet’s header, including the source and destination IP address, DPI examines the data within each packet and reassembles traffic sessions to gain insight into network activity. This allows IPS solutions to block a more excellent range of cyberattacks, such as phishing emails with dangerous attachments and IoT device exploitation in DDoS attacks.
However, DPI can add a layer of complexity to current firewalls and security software, requiring databases to be routinely updated with details about fresh threats. Moreover, it can also lead to false positives. However, they can be reduced by establishing appropriate baseline behaviors for network components, creating conservative policies and custom thresholds, and routinely evaluating warnings and reported incidents. Furthermore, the technology has been used for less-than-admirable purposes, such as eavesdropping and censorship by Chinese authorities. This has been a significant concern for privacy advocates and opponents of net neutrality.
