Networks attacks and vulnerabilities

The worst network attacks can pose indefinite data extraction risks that will take a complete system overhaul to patch.

“Every data loss is a new attack vector,” said Keensmith. “Before, the damage was contained to one connection. If they can use these channels to see what ports are open, they can perform various techniques with the information.”

Meanwhile, ISPs are increasingly logging your activity for example, by connecting a wifi sniffer to your home router. They’re also collecting details about your application usage which apps you’ve used, for how long, and what you do in them. If a network attacker is collecting this information, then they can mine it for patterns and suss out users.

Both of these issues are much harder to fix than simple port scanning. They require a complete overhaul of the protocol, because the way it’s designed it’s difficult to audit what happens under the hood.

Most serious internet attacks require that the compromise of the security systems used to protect the networks at a network edge affects the entire network, and that’s why getting the right protection for your network is essential, and you can find it in sites such as https://www.fortinet.com/products/management/fortimanager that specialize in this area.

“The attack will gain access to your network even if you can’t use it right away, so you have to keep the gateways and the core operational,” said Ferrer. “This is actually one of the biggest ways that we’re able to combat this type of attack.”

Some companies are starting to take action to protect themselves against attacks on their networks, but several others are currently experiencing widespread downtime in the wake of the Flashback. And the industry as a whole isn’t expected to fix the problem for at least a few years.

Network vendors in both academia and business are recognizing that, in order to better protect against the attacks and make the networks more resilient, they need to develop more security architecture in software and firmware, but there’s also a growing realization that it takes massive investments to ensure the network is prepared for such attacks.

“We’re seeing a big shift in the way that network operators think about security,” said Prosser. “A few years ago, networks didn’t think about security in this context. Now they’re thinking of security in a broader sense: the challenges to providing the service, their interactions with customers and partners, and the impact to the security environment.”

The increasing complexity of vulnerabilities

A quick glance at the world’s firewall compliance and security frameworks will see many tools meant to stop network attackers from hijacking users. But many of these existing solutions are designed for modern systems that will be hard-pressed to keep up with any advanced malware and DDoS attacks.

The infrastructure is also evolving rapidly, and one of the critical ways it’s evolving is through the adoption of more network-centric security technologies like Security Configuration Management and Network Service Discovery.

This shift stems from the realization that the threat landscape is much more complex now. The standards created decades ago to reduce the attack surface now need to be augmented to protect against the more subtle threats. This time, many security industry observers predict that many of the existing efforts to prevent attacks will end up backfiring in the years to come.

“A single network-based vulnerability like a zero-day would have taken weeks or months to infect a device,” said Ryan Conrad, executive director of the Internet Infrastructure Project (IIP). “We’re in a world of new threats and it’s incredibly difficult to foresee the result of a single vulnerability.”
