Software is rarely a one-and-done proposition. In fact, any application available today will likely need to be updated – or patched – to fix bugs,  address vulnerabilities , and update key features at multiple points in the future. With the typical enterprise relying on a multitude of applications, servers, and end-point devices in their day-to-day operations, the acquisition of a robust  patch management platform  to identify, test, deploy, install, and document all appropriate patches are critical for ensuring systems remain stable and secure.  As with most tech tools, not all patch management solutions are created equal, and what's seen as robust by one organization may prove inadequate for another. However, an evaluation that begins with a focus on specific key criteria – essential attributes and functionality likely to be offered by many vendors but not all – will allow IT teams to narrow down their options as they work to identify the best solution for thei...

If you spend more than a few hours a month doing patching; if you stay up until the middle of the night one Saturday each month doing patching; if you just flip on automatic updates and hope for the best; or if you email your users instructions on how to update their machines – then you're doing it wrong. Patching shouldn't be something that takes multiple days, nor is it something that should ruin one weekend a month. But it is critical and needs to be done right. If you think you're spending way too much time on patching, and have actually considered skipping a month because things didn't sound "that bad," then here's a post just for you. In it, we'll look at seven tips to save you time (and money) taking care of patch management. 1. Have a plan: First of all, you have to have a plan. Management has to support it, and you need to make sure it covers all the systems on your network. You don't want to patch at random, or try to remember every system that you have. Create a plan that...

9 Top Patch Management Practices for Businesses Security I've spent most of the past decade in information security, with a pretty big focus on incident response. It never ceases to amaze me how many security incidents (pronounced hacks) customers suffer as a result of unpatched systems. Patch management is not an art form; it's an underappreciated and often ignored part of what should be daily care and feeding of your infrastructure. Here are the nine best patch management practices I've learned over the years: 1. Automate your patching If your patch management strategy depends upon manual effort, you're doing it wrong. Only the smallest businesses can handle patching by hand. You need a system that can deploy patches to all your systems; workstations and servers. 2. In-depth reporting Automating doesn't mean ignoring. You should be able to see the state of your patch management at any point in time and know exactly which systems are in need of attention. 3. Tes...

You've got to ask yourself one question. How much hassle does patching cause you? Is the second Tuesday of each month something you dread, or is it just another day for you? If you spend days and days testing and deploying patches; if you stay up until the wee hours of the morning one weekend each month; if you have a current profile on every single server in your environment; then patching is likely to be a heavy burden. But there is another way. Patching is not something that should be a major pain each month. It should be a simple and straightforward administrative task. Admins who patch by hand or are worried about some patch crashing critical systems each month should consider automated patch management. This strategy will boost efficiency and give you back your weekends, and ensure that your systems can be patched quickly, efficiently and safely. Automated patch management helps IT admins patch their servers and workstations in the most efficient way possible, by removi...

It's no secret that keeping software up to date is one of the key best practices in cybersecurity. Software vulnerabilities are being discovered almost weekly these days. The longer it takes IT teams to apply updates issued by developers to patch these security flaws, the more time attackers have to exploit the underlying vulnerability. Once threat actors gain access to corporate IT ecosystems, they can steal or encrypt sensitive data, deploy ransomware, damage systems, and more. When there's a known exploit for a critical vulnerability, the need to deploy patches becomes critical. At the same time, while IT teams race to keep their operating systems, business applications, and web browsers up to date and fully patched, they have to exercise caution, since applying patches without proper testing can introduce more problems than it solves. The reality is, many organizations are struggling to maintain the upper hand against threats. According to Action1's  2021 Remote IT ...

Wanna hack someone's Android smartphone by sending just an MMS message? Yes, you can, because Google's patch for the Stagefright vulnerability in hundreds of Millions of Android devices is BUGGY. Last week, Google issued an official patch for Stagefright vulnerability that affects 95 percent of Android devices running version 2.2 to version 5.1 of the operating system, an estimated 950 Million Android devices in use worldwide. But, the patch is so flawed that hackers can still exploit the Stagefright vulnerability (CVE-2015-3824) anyways. "The [original] patch is four lines of code and was (presumably) reviewed by Google engineers prior to shipping," researchers at Exodus Intelligence wrote in a blog post published Thursday. "The public at large believes the current patch protects them when it, in fact, does not." Buggy Patch Issued by Google The patch doesn't fix the vulnerability, allowing booby-trapped MP4 videos that supplied...

The Vulnerability reported on 06/12/2012, dubbed as " CVE-2012-0217 " - according to that Some 64-bit operating systems and virtualization software running on Intel CPU hardware are vulnerable to a local privilege escalation attack. The vulnerability may be exploited for local privilege escalation or a guest-to-host virtual machine escape. FreeBSD/amd64 runs on CPUs from different vendors. Due to varying behaviour of CPUs in 64 bit mode a sanity check of the kernel may be insufficient when returning from a system call. Successful exploitation of the problem can lead to local kernel privilege escalation, kernel data corruption and/or crash. Inj3ct0r team today released related private exploit on their website , which allow normal FreeBSD users to Privilege Escalation. All systems running 64 bit Xen hypervisor running 64 bit PV guests onIntel CPUs are vulnerable to this issue. However FreeBSD/amd64 running on AMD CPUs is not vulnerable to thisparticular problem.Systems w...

Cybersecurity teams have many demands competing for limited resources. Restricted budgets are a problem, and restricted staff resources are also a bottleneck. There is also the need to maintain business continuity at all times. It's a frustrating mix of challenges – with resources behind tasks such as patching rarely sufficient to meet security prerogatives or compliance deadlines. The multitude of different security-related standards have ever stringent deadlines, and it is often the case that business needs don't necessarily align with those requirements. At the core of what TuxCare does is automated live patching – a way to consistently keep critical services safe from security threats, without the need to expend significant resources in doing so, or the need to live with business disruption. In this article, we'll outline how  TuxCare  helps organizations such as yours deal better with security challenges including patching, and the support of end-of-life operating s...

Brace yourselves for a possible 'second wave' of massive global cyber attack, as SMB ( Server Message Block) was not the only network protocol whose zero-day exploits created by NSA were exposed in the Shadow Brokers dump last month. Although Microsoft released patches for SMB flaws for supported versions in March and unsupported versions immediately after the outbreak of the WannaCry ransomware, the company ignored to patch other three NSA hacking tools, dubbed " EnglishmanDentist ," " EsteemAudit ," and " ExplodingCan ." It has been almost two weeks since WannaCry ransomware began to spread, which infected nearly 300,000 computers in more than 150 countries within just 72 hours, though now it has been slowed down. For those unaware, WannaCry exploited a Windows zero-day SMB bug that allowed remote hackers to hijack PCs running on unpatched Windows OS and then spread itself to other unpatched systems using its wormable capability. ...

A short-lived phishing campaign has been observed taking advantage of a novel exploit that bypassed a patch put in place by Microsoft to fix a remote code execution vulnerability affecting the MSHTML component with the goal of delivering Formbook malware. "The attachments represent an escalation of the attacker's abuse of the CVE-2021-40444 bug and demonstrate that even a patch can't always mitigate the actions of a motivated and sufficiently skilled attacker," SophosLabs researchers Andrew Brandt and Stephen Ormandy  said  in a new report published Tuesday. CVE-2021-40444  (CVSS score: 8.8) relates to a remote code execution flaw in MSHTML that could be exploited using specially crafted Microsoft Office documents. Although Microsoft addressed the security weakness as part of its September 2021  Patch Tuesday updates , it has been put to use in  multiple attacks  ever since details pertaining to the flaw became public. That same month, the technology g...

It's Patch Tuesday—time to update your Windows devices. Microsoft has released a large batch of security updates as part of its November Patch Tuesday in order to fix a total of 53 new security vulnerabilities in various Windows products, 19 of which rated as critical, 31 important and 3 moderate. The vulnerabilities impact the Windows OS, Microsoft Office, Microsoft Edge, Internet Explorer, Microsoft Scripting Engine, .NET Core, and more. At least four of these vulnerabilities that the tech giant has now fixed have public exploits, allowing attackers to exploit them easily. But fortunately, none of the four are being used in the wild, according to Gill Langston at security firm Qualys . The four vulnerabilities with public exploits identified by Microsoft as CVE-2017-8700 (an information disclosure flaw in ASP.NET Core), CVE-2017-11827 (Microsoft browsers remote code execution), CVE-2017-11848 (Internet Explorer information disclosure) and CVE-2017-11883 (denial of ser...
