How 802.11ac Wave 2 Complicates WiFi Troubleshooting

For all intents and purposes, 802.11ac has been a great success. Since its approval by the IEEE nearly two years ago, the WiFi standard has introduced thousands of compatible routers, laptops, mobile phones, IoT devices and other wireless gadgets operating at blazing speeds in the 5 GHz band. And the revolution has just begun.

Examining the scene of the (cyber) crime with network forensics

Enterprise security teams have historically spent most of their time, human resources, and money on defences like firewalls and Intrusion Detection Systems (IDS) to protect and monitor the security of their networks. However, a quick look at the news will tell you that these barriers are far from foolproof. With breaches becoming more common (and costly), enterprise teams are turning to tools that help them respond quickly to security incidents as soon as the attack has been discovered. Network forensics looks at information such as log data, network flow, and packet data to answer the question ‘how did the attackers get in?’

Cyberattack CSI: Forensics investigations should start with pre-attack analysis

Enterprise security teams have historically spent a lot of time, human resources, and money on developing strong defenses such as firewalls and deploying equipment and software like intrusion detection systems (IDS) to monitor the security of their networks. In fact, most enterprises have built an impressive level of expertise when it comes to configuring and monitoring these tools.

Nevertheless, as we all know, breach detection and prevention technologies are not foolproof. Given attackers’ success in penetrating standard corporate defenses, enterprise teams are looking beyond these well-known technologies and incorporating better tools and training that deal specifically with incident response once attacks have been discovered.

The LTE-U Vs. WiFi Debate

LTE-U, an emerging technology that aims to reduce cell phone data congestion by offloading traffic onto unlicensed spectrum, has been a hot topic in the wireless world. Carriers like AT&T, T-Mobile and Verizon are proponents of rolling out this technology while wireless companies and coalitions like the Wi-Fi Alliance worry that it will degrade WiFi performance. In fact, they have gone so far as to say that LTE-U would be disastrous. Is this just hype, or a valid concern? It may be too early to tell, but let’s look at what we know so far.
