Is Your Company Protected From a DDoS Attack?

The distributed denial of service (DDoS) attack staged by the Mirai botnet in the fall of 2016 is legendary for its scale and reach. Hackers managed to weaponize thousands of unsecured IoT devices. The botnet was then used to flood the internet with traffic, crippling large businesses all over the world, including Dyn, a company that hosts domain name systems (DNS) for major websites.

When reporting on a more recent DDoS attack, Dark Reading noted that these attacks are becoming more difficult to fight because they are growing in speed and intensity and use multiple source addresses and ports.

how does a ddos attack work?

Your company may feel it is doing enough to protect itself against a DDoS attack, but is it?

Even if you are using a firewall with an intrusion detection system (IDS) and intrusion prevention system (IPS), you still may not be doing enough to stop a DDoS attack. Fighting a DDoS attack with a firewall may actually make your organization more vulnerable or disrupt your business further.

The Downside to Firewalls

 downsides-to-firewallsFirewalls may seem to be an ideal defense against DDoS attacks. After all, firewalls are designed to keep suspicious network traffic from breaching the perimeter of company systems. The firewall filters incoming packets of information, checking to see if they meet specific criteria before allowing them through. However, when confronted with excessive traffic, the firewall may slow the transmission process down even further, leading to disruptive downtime.

Firewalls may even serve as entry points for DDoS attacks. The firewall ports that are intended to allow authorized traffic to enter may enable DDoS traffic to slip through.

Prevention and Recovery: How can security tools help?

 Heavy rains, floods, landslides, devastating fires, blackouts that left an entire state without electricity. Unfortunately, the list of disasters that occurred in Brazil during the year 2020 is long. Disasters appear unexpectedly, generating terrible results and, often, irreversible damage. Within a company's scenario, it is not much different. Just as nature is subject to disasters and risks, so are companies. Therefore, information security works to protect data and information within the business environment, through tools and actions that act in the prevention and recovery of data in disaster situations. In this article, you will understand how security tools can help in a disaster scenario, and why it is important to have complete and continuous actions to protect your company's data.

How to increase visibility and mitigate risks in the corporate network?

 Corporate networks are changing rapidly as companies embark on Digital Transformation, expanding on the Cloud, incorporating IoT devices and increasing wireless access. All of this increases the attack surface, making the environments more complex.  Protecting this new environment and blocking more sophisticated and intelligent cyber threats has been a major challenge for IT. Therefore, it is necessary to invest in tools capable of giving quick and accurate responses to any type of attack. The problem is that, as the context and visibility are compromised by the complexity of the environment, the IT team ends up having trouble screening many alerts at the same time.  As a result, response times are delayed and teams are often unable to accurately screen all alerts, allowing potential threats to go unnoticed. To deal with this new reality, companies need robust and efficient protection solutions, such as Gigamon's ThreatINSIGHT. It is the cloud's first native high-speed network
