Carbon Black specializes in offering comprehensive endpoint security features, including threat hunting and incident response.

Anti-ransomware tools employ methods such as Behavioral Analysis, Anomaly detection and machine learning to detect cyber threats, particularly ransomware attacks: 1. Behavioral Analysis: Anti-ransomware tools monitor system behavior to detect suspicious activities indicative of ransomware, such as mass file encryption or unusual file access patterns. 2. Anomaly Detection: Anti-ransomware tools look for anomalies in file access, encryption behavior, or network traffic that may indicate a ransomware attack in progress. 3. Machine Learning: Some anti-ransomware solutions utilize machine learning algorithms and artificial intelligence to analyze file behavior and identify ransomware-like patterns, even in previously unseen threats.

ModSecurity, open-source, anchors the web application firewalls of major cloud providers. It uses rule sets such as the OWASP CRS, favored for strong security. OpenAppSec, Checkpoint's open-source project, applies machine learning to protect applications from web threats. The rise of WAAP underlines the need for API security, emphasising deep inspection of data formats like JSON, XML, gRPC, and others to secure applications. API aware security is the future. My company, Peakhour in Australia, introduces a hybrid WAF. It merges machine learning with CRS-based rules for swift, effective defense against zero-day attacks.

Cloudflare, Imperva, and Sucuri serve as critical defenses for web applications, protecting against common attacks such as SQL injection and cross-site scripting. Cloudflare offers a range of security features including DDoS protection and a WAF that shields websites from harmful traffic. Imperva provides application and data protection, ensuring secure delivery of content. Sucuri emphasizes website security, offering malware removal and attack prevention to maintain the integrity of web applications.

WAF tools are essential for perimeter protection. In many cases, a feature of this type mitigates vulnerabilities and development flaws, such as untreated data input, XSS exploits and several other attacks, such as OWASP Top 10. In addition to this type of defense, tools such as Akamai protect against Bot attacks, DoS and generates visibility of API calls, a fundamental point for defending the current environment.

Intelligence tools are fundamental in complementing information and generating vision of emerging threats, supporting both indicators for consumption of correlation tools and visibility of technical teams so that, through specific actions generated by an emerging attack, we can block a threat before it is explored in an environment.

SIEM desempenham um papel essencial na detec??o e resposta a incidentes de seguran?a. Op??es líderes pagas, como Splunk, IBM QRadar e LogRhythm, oferecem recursos avan?ados para coleta, correla??o e análise de dados de eventos, possibilitando a identifica??o rápida de padr?es suspeitos. Já no ambito de código aberto, o ELK Stack (Elasticsearch, Logstash e Kibana) destaca-se pela sua flexibilidade e escalabilidade na ingest?o e visualiza??o de grandes volumes de dados de eventos de seguran?a. A escolha entre solu??es pagas e de open source dependerá das necessidades específicas da organiza??o, or?amento e requisitos de conformidade, sendo crucial investir em ferramentas SIEM para fortalecer a seguran?a.

SIEM tools also provide real-time monitoring of incidents collected and analysed from various sources such as networks, logs and events, systems, firewalls etc. and checks for unusual activity that could indicate cyber threats. For instance, user clicked on malicious email link or MFA failed etc. When SIEM tools detect something suspicious, it immediately sends an alert to the security monitoring team or SOC team to take the action along with the severity defined for each alert inorder to give the understanding of the alert/incident detected and their potential impact that can harm the organisation. Thus, pushing the SOC team to respond to the alert to mitigate the potential harm thereby helping to detect cyber threats.

Although many currently say that an XDR can replace a SIEM, I believe that it still has a great strength in the visibility and correlation of events in an environment. Due to its ability to integrate, correlate and automate together with a SOAR, it can generate an operational gain and a reduction in the SLA for responding to a security incident, due to its comprehensive connectivity and improved correlation with onboard threat intelligence.

APIs have become a common target for attackers due to their increasing use in modern web and mobile applications. API protection tools are able to monitor incoming and outgoing API traffic to detect any anomalies or suspicious patterns that may indicate malicious activity. Additionally, they can validate incoming requests against the API schema to detect malformed or malicious requests. Overall, API protection tools play a crucial role in safeguarding APIs and the applications that rely on them against cyber threats, ensuring the integrity, availability, and confidentiality of API resources.

The detection of cyber threats is of greater interest and greater effectiveness when they are located in the adversary's reconnaissance. It is when we establish the attacker's intentions and capabilities that cyberthreats make sense. Listing cyber threats or detecting them is not an exercise that is done in a vacuum, it responds to an analysis and exploration of the environment where it is indeed feasible to warn of possible effects and actions that may end up affecting the company. Although there are threat intelligence services, this will not be more effective if it is only a technical report that is not located in the reality of the company.

They are free and paid tools and you should consider reviewing and testing them and observe your requirements and resources and them decide on which tools you will need to implement.
