Published

Cisco, the company’s whose products underpin a large chunk of today’s internet and enterprise sector, has published today 15 security updates for some of its products.

Of the 15 security updates released to customers today, two vulnerabilities allow attackers to gain root access on the device, while the third bypasses authentication altogether.

The two root access-granting bugs impact Cisco HyperFlex, a piece of software for linking data centers together for easier data and resource sharing.

The most critical of the two flaws is the one tracked under the identifier of CVE-2018-15380, which also has a severity rating of 8.8 on a scale of 1 to 10.

“A vulnerability in the cluster service manager of Cisco HyperFlex Software could allow an unauthenticated, adjacent attacker to execute commands as the root user,” Cisco said.

The company pinned the bug on insufficient input validation when processing user commands, and issued a security update today to address the issue.

The second HyperFlex issue is tracked as CVE-2019-1664, has a severity rating of 8.1, and was discovered during internal Cisco security testing (just like the first).

Cisco says the vulnerability resides in the hxterm service of the Cisco HyperFlex software package and it can “allow an unauthenticated, local attacker to gain root access to all nodes in the cluster.”

The third vulnerability (CVE-2019-1662) that we chose to highlight for this article impacts Cisco’s Prime Collaboration Assurance (PCA) software, one of the company’s many team collaboration suites.

According to Cisco, the PCA software’s Quality of Voice Reporting (QOVR) service contained a vulnerability that when exploited could allow an attacker to gain access to accounts just by entering a valid username, with no need to enter the associated password.

Updates for the three flaws and the other 12 have been made available. None of the 15 vulnerabilities Cisco patched today were under active exploitation by hacker groups.

Most Cisco vulnerabilities tend to enter the “exploitation phase” a few days or weeks after being patched, and after security researchers publish proof-of-concept code that hackers quickly weaponize.

Something like this happened at the end of last month when proof-of-concept code published on GitHub after Cisco patched a vulnerability led to immediate attacks against Cisco RV320 and RV325 routers.

In 2018, Cisco removed seven backdoor accounts from various products, most of which had been discovered by its own staff following internal security audits.

GigaOm Radar for DDoS Protection

Published

on

With ransomware getting all the news coverage when it comes to internet threats, it is easy to lose sight of distributed denial of service (DDoS) attacks even as these attacks become more frequent and aggressive. In fact, the two threats have recently been combined in a DDoS ransom attack, in which a company is hit with a DDoS and then a ransom demanded in exchange for not launching a larger DDoS. Clearly, a solid mechanism for thwarting such attacks is needed, and that is exactly what a good DDoS protection product will include. This will allow users, both staff and customers, to access their applications with no indication that a DDoS attack is underway. To achieve this, the DDoS protection product needs to know about your applications and, most importantly, have the capability to absorb the massive bandwidth generated by botnet attacks.

All the DDoS protection vendors we evaluated have a cloud-service element in their products. The scale-out nature of cloud platforms is the right response to the scale-out nature of DDoS attacks using botnets, thousands of compromised computers, and/or embedded devices. A DDoS protection network that is larger, faster, and more distributed will defend better against larger DDoS attacks.

Two public cloud platforms we review have their own DDoS protection, both providing it for applications running on their public cloud and offering only cloud-based protection. We also look at two content delivery networks (CDNs) that offer only cloud-based protection but also have a large network of locations for distributed protection. Many of the other vendors offer both on-premises and cloud-based services that are integrated to provide unified protection against the various attack vectors that target the network and application layers.

Some of the vendors have been protecting applications since the early days of the commercial internet. These vendors tend to have products with strong on-premises protection and integration with a web application firewall or application delivery capabilities. These companies may not have developed their cloud-based protections as fully as the born-in-the-cloud DDoS vendors.

In the end, you need a DDoS protection platform equal to the DDoS threat that faces your business, keeping in mind that such threats are on the rise.

GigaOm Radar for Security Information and Event Management (SIEM) Solutions

Published

on

The security information and event management (SIEM) solution space is mature and competitive. Most vendors have had well over a decade to refine their products, and the differentiation among basic SIEM functions is fairly small.

In response, SIEM vendors are developing advanced platforms that ingest more data, provide greater context, and deploy machine learning and automation capabilities to augment security analysts’ efforts. These solutions deliver value by giving security analysts deeper and broader visibility into complex infrastructures, increasing efficiency and decreasing the time to detection and time to respond.

Vendors offer SIEM solutions in a variety of forms, such as on-premises appliances, software installed in the customers’ on-premises or cloud environments, and cloud hosted SIEM-as-a-Service. Many vendors have developed multi-tenant SIEM solutions for large enterprises or for managed security service providers. Customers often find SIEM solutions challenging to deploy, maintain, or even operate, leading to a growing demand for managed SIEM services, whether provided by the SIEM vendor or third-party partners.

SIEM solutions continue to vie for space with other security solutions, such as endpoint detection and response (EDR), security orchestration automation and response (SOAR), and security analytics solutions. All SIEM vendors support integrations with other security solutions. Many vendors also offer tightly integrated solution stacks, allowing customers to choose the solutions they need most, whether just a SIEM, a SIEM and a SOAR, or some other combination. Other vendors are incorporating limited EDR- or SOAR-like capabilities into their SIEM solutions for customers who want the extra features but are not ready to invest in multiple solutions.

With so many options, choosing a SIEM solution is challenging. You will have to consider several key factors, starting with your existing IT infrastructure. Is an on-premises SIEM the right choice for you, or do you want a cloud-based or hybrid solution? Which systems and devices will be sending data to your SIEM, and how much data will it need to collect, correlate, analyze, and store? You should also consider the relative importance of basic capabilities and advanced features, bearing in mind that the basic capabilities may be considerably easier to deploy, maintain, and operate. Will your IT and security teams be able to deploy, maintain, and operate the solution on their own, or should you look for managed services to handle those tasks?

This GigaOm Radar report details the key SIEM solutions on the market, identifies key criteria and evaluation metrics for selecting a SIEM, and identifies vendors and products that excel. It will give you an overview of the key SIEM offering and help decision-makers evaluate existing solutions and decide where to invest.

Key Criteria for Evaluating a Distributed Denial of Service (DDoS) Solution

Published

on

Although ransomware is making all the headlines today, it’s not the only kind of attack that can intrude between you and your customers. Distributed denial of service (DDoS) attacks, in which a target website is overwhelmed with spurious traffic, have become increasingly common.

Websites and online applications have become critical to how businesses communicate with their customers and partners. If those websites and applications are not available, there is a dollars and cents cost for businesses, both directly in business that is lost and indirectly through loss of reputation. It doesn’t matter to the users of the website whether the attacker has a political point to make, wants to hurt their victim financially, or is motivated by ego—if the website is unavailable, users will not be happy. Recent DDoS attacks have utilized thousands of compromised computers and they can involve hundreds of gigabits per second of attack bandwidth. A DDoS protection platform must inspect all of the traffic destined for the protected site and discard or absorb all of the hostile traffic while allowing legitimate traffic to reach the site.

Often the attack simply aims vast amounts of network traffic at the operating system under the application. These “volumetric” attacks usually occur at network Layer 3 or 4 and originate from compromised computers called bots. Few companies have enough internet bandwidth to mitigate this much of an attack on-premises, so DDoS protection needs to be distributed to multiple data centers around the world to be effective against these massive attacks. The sheer scale of infrastructure required means that most DDoS platforms are multi-tenant cloud services.

Other attacks target the application itself, at Layer 7, with either a barrage of legitimate requests or with requests carefully crafted to exploit faults in the site. These Layer 7 attacks look superficially like real requests and require careful analysis to separate them from legitimate traffic.

Attackers do not stand still. As DDoS protection platforms learn to protect against one attack method, attackers will find a new method to take down a website. So DDoS protection vendors don’t stand still either. Using information gathered from observing all of their protected sites, vendors are able to develop new techniques to protect their clients.
