WPA security explained: what is Wi-Fi Protected Access?

WiFi signals can be put into two different categories, unencrypted and encrypted. Unencrypted WiFi, sometimes known as open WiFi, can be connected to without a password. Anyone with a phone, tablet, PC, video game system, or Internet of Things device within range of the open WiFi signal can use it as long as there aren’t more devices connected to the wireless access point than it can handle. But the data being sent to and from your device through the open WiFi signal is unencrypted.

Types of Wireless Network Attacks

Wireless networks have become an integral part of how we conduct our businesses.

Wireless technologies offer convenient solutions to our needs. They are practical and fast, moreover they set us free of the clutter caused by wires and cables. On the other hand, it is no secret that wireless networks are more vulnerable to attacks and intruders.

What is Encapsulating Security Payload in Network Security?

Being one of the most popular tools used in network security, Encapsulating Security Payload (abbreviated as ESP) offers the help we need in keeping the integrity, authenticity and confidentiality of the information we send across networks. Keep reading to learn more! With the technological advancements, the way we conduct our business processes has changed immensely. Now, we heavily rely on the internet technologies and transfer massive amounts of data daily.

How to Detect Open Ports, Protocols and Services

IT Services rely on an individual port assigned to them in order to receive and transmit information, therefore, it’s imperative that an organization keeps track of what ports are open within their IT environment, the function of the port and what services it’s associated with. Detecting and disabling unwanted ports is part of an ongoing hardening process.

Stories from the SOC - detecting network anomalies with OTX

Creating security policies for the devices connected to your network is critical to ensuring that company data is safe. This is especially true as companies adopt a bring-your-own-device model and allow more personal phones, tablets, and laptops to connect to internal services. These devices, or endpoints, introduce unique vulnerabilities that can expose sensitive data if they are not monitored.

What is an SMB Port + Ports 445 and 139 Explained

The Server Message Block Protocol (SMB Protocol) is a client-server communication protocol used for sharing access to files, printers, serial ports, and data on a network. It can also carry transaction protocols for authenticated inter-process communication. In short, the SMB protocol is a way for computers to talk to each other. SMB works through a client-server approach, where a client makes specific requests and the server responds accordingly. This is known as a response-request protocol.
