Oh no! You’ve been hacked, and you have experts onsite to identify the terrible things done to your organization. It doesn’t take long before the beardy dude or cyber lady says, “Yeah...they used DNS to control compromised hosts and then exfiltrated your data.” As you reflect on this event, you think, “Did I even have a chance against that kind of attack?” Yes, you did because Splunk can be used to detect and respond to DNS exfiltration.

Authentication and authorization are two key processes that ensure only trustworthy and verified users can gain access to authorized system resources and data. They enable your organization’s information security — your ability to protect sensitive information against unauthorized access. Although these two processes are used interchangeably, they have several fundamental differences.

At one time, the internet was seen as a place where users could remain anonymous: they could scroll from the privacy of their screen. Today, we know that’s no longer the case. In an attempt to sell more products, and create a personalized digital experience, tech firms, companies and advertisers track and analyze each user across the digital landscape. Privacy is still important to users: 90% of individuals in a recent global survey said online privacy was important to them.

On May 19, 2023, Barracuda Networks identified a remote command injection vulnerability (CVE-2023-2868) present in the Barracuda Email Security Gateway (appliance form factor only) versions 5.1.3.001-9.2.0.006. In its security advisory, Barracuda said the vulnerability existed in the Barracuda software component responsible for screening attachments for malware. In subsequent days, Barracuda deployed a series of patches.

The vastness of the deep and dark web can easily turn attempts to monitor for cyber threats into a firehose of useless information. Part of the problem is the nature of the data streams that need to be monitored. Every day, more credentials are stolen and exposed. Illegal criminal forums are full of repeated spamming of illicit advertisements. Thousands of new domain names are registered daily, including many that can be considered typosquatted.

The recent discovery of a zero-day vulnerability in a well-known email security product further underscores the importance of robust email security that can effectively counter advanced email threats, offer a defense-in-depth approach, and operate in the cloud or on-premises. To start, if you believe you have suffered a breach, Trustwave’s Digital Forensics and Incident Response (DFIR) is ready and online to take your call and start helping your organization recover.

A disruption to your company’s information technology (IT) systems can disrupt your business operations as well, costing you time and money while employees wait for repairs. An audit of your IT systems can identify and fix those potential disruptions before they happen – and an IT audit checklist can assure that your IT department has the necessary resources in place to keep your systems safe.

Protecting endpoints is more important than ever, as existing threats like ransomware continue to damage organizations and emerging threats like AI-driven attacks add to the problem. As attackers find new ways to exploit an organization’s vulnerabilities, IT security teams find themselves under pressure to act quickly, often searching for new tools. However, when security solutions are bolted together hastily, problems arise.

If you’re shopping around for a way to stop bots damaging your brand – be that through enabling automated fraud, hoarding your stock, scraping your content or prices, or just eating up server resources – you’ve probably seen vendors advocating the use of “client-side detection”. They’re probably telling you it’s necessary for accurate bot detection.

The protection of sensitive information is critical for any organization, especially when it involves national defense. The effort is not only for protecting the information but also ensuring that the organization meets regulatory compliance and policies. The US government’s efforts to break down information silos and improve sharing of data have led to an increase in the number and diversity of people accessing and working with CUI.
