How SecurityScorecard’s cybersecurity monitoring enables defense in depth strategies


Suggestions for creating a defense in depth strategy for ports

As part of your defense in depth strategy that protects against attackers targeting ports, you should be continuously monitoring for:
·         Unused open ports
·         Host-based firewalls
·         Network-based firewalls
·         Port traffic filtering
·         Strong passwords
·         Access controls
·         Penetration testing
While all of these suggestions seem simple, your interconnected IT infrastructure complicates them. For example, adding more devices increases the number of ports which in turn means you need to continuously scan for unused ports. Firewalls control the way information flows across your network, but they also lead to application visibility and control issues.

Cybersecurity monitoring enhances defense in depth strategies

Continuously monitoring controls effectiveness is the only way to ensure that your defense in depth strategies protect data security. Three of the primary controls that protect against a data breach - unused open ports, host-based firewalls, network-based firewalls - often require manual processes and review to ensure their continued effectiveness.

What does cybersecurity monitoring do?

Unused open ports often remain unnoticed because organizations lack the capability to continuously scan their networks. Digital transformation objectives leave you adding and removing services on a regular basis. Monitoring the ports that these services use can become overwhelming when done manually, ultimately creating a human error risk that can lead to a data breach.

Importance of threat intelligence in cybersecurity

Cyber threat intelligence helps organizations by giving them insights into the mechanisms and implications of threats, allowing them to build defense strategies and frameworks, and reduce their  attack surface  with the end goals of mitigating harm and protecting their network. The main objective of cyber threat intelligence is to provide organizations a deeper understanding of what’s happening outside their network, giving them better visibility of the cyber threats that bring the most risk to their infrastructure. You need threat intelligence for effective defense. It’s also about prioritizing: removing false positives that constantly hit SOCs and recognizing the advanced threats and exploits the organization is most vulnerable to, so teams can take action against them. With cyber threat intelligence, you can determine if your security defense system can actually handle those threats, and improve it as necessary. Here are other major benefits to good cyber threat in...

Machine Learning for Better Threat Intelligence

Data processing takes place at a scale today that requires automation to be comprehensive. Combine data points from many different types of sources — including open, dark web, and technical sources — to form the most robust picture possible. Recorded Future uses  machine learning  techniques in four ways to improve data collection and aggregation — to structure data into categories, to analyze text across multiple languages, to provide risk scores, and to generate predictive models. 1. To structure data into entities and events Ontology has to do with how we split concepts up and how we group them together. In data science,  ontologies  represent categories of  entities  based on their names, properties, and relationships to each other, making them easier to sort into hierarchies of sets. For example, Boston, London, and Gothenburg are all distinct entities that will also fall under the broader “city” entity. If entities represent a way to sort p...

The most Important Challenges Facing Cyber Security

Cybersecurity researchers and business owners are now identifying attacks and threats that could affect the cybersecurity world in 2019. With only two months left until the end of the year, cybersecurity researchers and business owners are now looking to identify attacks and threats that could affect the cybersecurity world in the year 2020. Increased Cybercrime Throughout the year, as a result of the decisive failure of governments, international communities, and the United Nations, cybercrime by hacker groups backed will continue to grow. Many organizations do not have the proper structure to counter these attacks. In such circumstances, cybersecurity teams should rely on data breach detection techniques. Cloud Technology Insecurity The insecurity of cloud technology started and will, unfortunately, continue in the future as well. As the production and deployment of large volumes of data across different sectors of the organization, their security will face many ...
