Deep packet inspection (DPI) refers to the method of examining the full content of data packets as they traverse a monitored network checkpoint. Whereas conventional forms of stateful packet inspection only evaluate packet header information, such as source IP address, destination IP address, and port number, deep packet inspection looks at fuller range of data and metadata associated with individual packets.
Traditional firewalls have been around for decades. But NGFWs, uninhibited by the same technology limits, take advantage of significant advancements in storage space, memory, and processing speeds. The feature set for NGFWs build upon traditional firewall features by including critical security functions like intrusion prevention, VPN, and anti-virus, and even encrypted web traffic inspection to help prevent packets containing malicious content from entering the network.
With the increase in frequency, sophistication, and cost of cyberattacks, the global focus on cybersecurity is at an all-time high. However, the goalposts for those tasked with protecting businesses have shifted. Hackers have a growing number of ways they can compromise a business and are frequently looking to move laterally within an organization, using credentialed (and often elevated) access.
One of the benefits of having your managed detection and response (MDR) service managed by AT&T Cybersecurity is the visibility into threats from a large number of customers of all sizes and across different industries. This allows the team to take what they learn from one customer and apply it to another. Our security operation center (SOC) analysts were able to use an OTX alarm and an AWS correlation rule to discover open ports on public facing servers for two different customers in 24 hours.
Bring your own device (BYOD) describes the practice of using a personal device such as a smartphone or tablet to conduct business on an organization's network or with its data. Organizations constantly walk a tightrope with their BYOD policies to balance employee productivity and satisfaction against the effective management of cybersecurity risks.
Not too long ago, the desktop computer was the primary computing device for enterprise employees. With the rise of mobile endpoints like smartphones, laptops and tablets, employees are connecting to corporate networks from a wide variety of places and devices. Today, especially with the popularity of the WFH (work from home) model, managing the multitude of mobile devices is more complicated than ever before. The statistics tell a sobering tale.
IDC recently published the IDC MarketScape: Worldwide Managed Security Services 2020 Vendor Assessment, in which primary author Martha Vazquez and team studied 17 organizations that offer MSS globally. The report provides a comprehensive look at the top MSSP vendors, including AT&T Cybersecurity, and how managed security services are evolving to meet the needs of customers today.
Cyberattacks are an almost daily occurrence for many IT and security professionals, and there are a host of different security solutions in the marketplace today that look to help companies detect and prevent those attacks. However, despite all the technology organizations have in place, their users remain their weakest link. Phishing is still one of the top initial attack vectors. Why?
Organizations are increasingly incorporating containers and Kubernetes into their IT infrastructure. As reported by ZDNet, Flexera’s “2020 State of the Cloud Report” found that about two-thirds (65%) of organizations were using Docker and that another 14% intended to begin using it at some point. Slightly fewer organizations (58%) were using Kubernetes at the time of the survey, by comparison, with 22% of participants saying they planned to adopt it.
Since the start of the Covid-19 pandemic, the use of video chat software like Zoom has increased to 300 million meetings held per day. Unfortunately, hackers have taken to crashing private meetings and flooding them with objectionable content — a phenomenon known as Zoombombing. If you’re planning a virtual event, it’s important to pay attention to potential security issues and follow safety tips to keep the experience as safe and secure as possible for everyone involved.
