What is Threat Intelligence and How It Helps to Identify Security Threats

What is Threat Intelligence and How It Helps to Identify Security Threats

November 07, 2015Wang Wei
Simply put, threat intelligence is knowledge that helps you identify security threats and make informed decisions. Threat intelligence can help you solve the following problems: How do I keep up to date on the overwhelming amount of information on security threats…including bad actors, methods, vulnerabilities, targets, etc.? How do I get more proactive about future security threats? How do I inform my leaders about the dangers and repercussions of specific security threats? Threat Intelligence: What is it? Threat intelligence has received a lot of attention lately. While there are many different definitions, here are a few that get quoted often: Threat intelligence is evidence-based knowledge, including context, mechanisms, indicators, implications and actionable advice, about an existing or emerging menace or hazard to assets that can be used to inform decisions regarding the subject's response to that menace or hazard. – Gartner   The set of data collected, assessed and app
Here's How SIEM Can Protect Your Privileged Accounts in the Enterprise

Here's How SIEM Can Protect Your Privileged Accounts in the Enterprise

October 20, 2015Wang Wei
It's inevitable. Most security threats eventually target privileged accounts. In every organization each user has different permissions, and some users hold the metaphorical keys to your IT kingdom. If the privileged accounts get compromised, it can lead to theft or sabotage. Because these accounts control delicate parts of your IT operations, and it is important to know who has privileges, what privileges they have, when they received access, and what activity they've done. This is where Security Information and Event Management (SIEM) software comes in handy. SIEM Monitors and Alerts on Privileged Account Activity Comprehensive monitoring of privileged accounts can be challenging because you need to monitor users who are administrators, users with root access, and users with access to firewalls, databases, services, automated processes, etc. With every additional user, group, and policy monitoring account activity gets increasingly difficult.

Crowd-Sourced Threat Intelligence: AlienVault Open Threat Exchange™ (OTX)

July 14, 2014Swati Khandelwal
For years, the systems and networks that run our businesses have been secured by the efforts of IT and security practitioners acting on their own. We continue to deploy the latest countermeasures, always trying to keep up with adversaries. Criminal attackers, on the other hand, have shared information quite successfully to facilitate their exploits. Couple this with the "attacker's advantage" of choosing where, when and how to launch attacks, and it is no surprise that collaborative hackers appear to be winning against even the largest companies, despite generous spending on security tools. As an industry, we need a threat-sharing solution that is open and available to everyone for the mutual benefit of all who contribute. With this goal in mind, AlienVault created the Open Threat Exchange™ (OTX) . What is the Open Threat Exchange (OTX)? OTX is an open information sharing and analysis network that provides real-time, actionable threat information submitted by over 8,

SIEM for One, SIEM for All

IT security is not a luxury; it's a necessity. While IT practitioners understand this and are on the lookout for effective security options for their network, security solutions manufacturers tend to serve the enterprise market and large companies more than they do smaller organizations and resource-constrained security teams. The reality is that 99% of IT security departments are resource-constrained in terms of budget, time, and staff. This situation directly aligns with the Security Information & Event Management (SIEM) market. With the scores of costly, appliance-based and enterprise SIEM solutions on the market, the majority of security teams find it difficult to adopt SIEM to strengthen network security. Even if they do manage to meet the high cost of a SIEM purchase, they end up acquiring a SIEM which is too big for their security needs. This means incurring additional appliance maintenance costs, IT staff overhead costs to manage the SIEM product, and training an

Vulnerability Management: Think Like an Attacker to Prioritize Risks

Attackers care about ROI – they want to accomplish their objective with the least investment of time and resources possible. The same is true for you - to most effectively manage vulnerabilities, you need to think like an attacker. Ask yourself: How would you go about compromising systems, exfiltrating valuable information and making money? What are the key assets in your network that you would target? How would you get to these assets? Attackers are looking for vulnerabilities that are exposed – ones offering them an easy way to penetrate your network and pivot into the truly valuable assets on your network. Although zero-day exploits are heavily publicized, attackers more often use older, proven exploits very effectively. Fortunately, many such exploits are well known and have clear remediation methods. So, how can you determine if a known vulnerability is actually exploitable? The key is to correlate system vulnerabilities with threat intelligence so you can prioriti

Importance of Logs and Log Management for IT Security

Importance of Logs and Log Management for IT Security

October 02, 2013Wang Wei
IT Security is the name of the game and no matter how big or small the size of your organization, you will always invest enough on securing certain aspects of your IT network. In many organizations, it starts with monitoring your network for vulnerabilities that may enter the network to access potentially sensitive information in the form of security attacks . For example, you may have firewalls as your first line of defense, followed by vulnerability management, intrusion detection and prevention systems, managing your network configurations and so on.  These are crucial because: Your routers can be easily breached without proper configuration and restrictions.  If a firewall isn't configured correctly, a hacker can easily spot a port that is accidentally left open and can gain access to the network.  Rogue access points, botnet malware and social engineering can make your wireless a porthole into your LAN. Why Logs? The very purpose of IT security is to be

Security Information & Event Management (SIEM) has evolved over the years to become one of the most trusted and reliable solutions for log management, security, and compliance. The demand for SIEM tools is constantly increasing within network and IT security teams. This is due particularly to the colossal surge of security breaches and cyber-attacks that impact corporations and cause financial loss and damaged reputations. When conducting research for an SIEM solution, it's important to be able to identify features that will enable effective detection, prevention, and response to security threats. Below, we'll discuss a number of critical topics to consider when selecting an SIEM solution. Log Correlation – The Heart of SIEM SIEM software works with the principle of log collection and correlation, therefore, it's important to ensure that log correlation happens effectively, in real time, and provides centralized visibility into potentially insecure and non-co

The Top Six Ways You Will Benefit From Event Log Monitoring

Systems on your network log data 24/7/365. Simply allowing logs to take up disk space, reviewing them only after something has happened and deleting logs when you run low on disk space are all the strategies of an admin doomed to always being in firefighting mode, reacting to bad things when they happen. Proactive log management can help an admin get into a proactive mode You know that event log monitoring is important, since all your systems and key applications log data. But since no two systems log to the same place, or in the same format, it's almost impossible to get ahead of the logging and actually pay attention to what is being logged. That's where event log monitoring comes into play; here's why: Aggregate your logs in a central location:  With logs spread across dozens or even hundreds of systems, there's no way you can manage them where they are. Event log monitoring applications can gather up all your logs in a central location, making them easy to analyze, store, and m
