6 Ways to Protect Your Networks Against DDoS Attacks
A DDoS attack can happen to anyone.
In the past, it has hit Twitter, Telegram, GitHub, and the BBC. Whole governments, like those of Ecuador and Estonia, have had their websites knocked out by it.
This is not a rare threat. Every year, numerous organizations suffer from targeted DDoS attacks, launched at them by malicious agents from unknown locations. It causes their websites and networks to shut down and makes them lose millions of otherwise productive hours.
That’s a lot of revenues foregone. In the United States alone, businesses lose $10 billion annually because of these incidents. And with these attacks growing in other parts of the globe, there’s reason to be wary of the threat that they pose.
Your organization could be at risk, regardless of where you are.
But what are DDoS attacks? How do they work?
What is a DDoS Attack?
A DDoS (Distributed Denial of Service) attack is a type of DoS attack.
In a DoS attack, a malicious agent attempts to overwhelm their victim’s networks with fake traffic. For instance, they could send a lot of false requests to the victim website. The aim here is to stuff the network so much that people with real requests cannot get through to the website.
A regular DoS is launched from a single user device. But in a DDoS, the human agent gains access to several devices (PCs or smartphones) by infecting them with malware, and use those devices (collectively called a ‘botnet’) to flood the victim’s network with fake requests.
When a network comes under attack in this way, its servers will either fail to perform optimally or crash.
What are the Types of DDoS Attacks?
There are two general groups of attacks in this category:
- Network Layer Attacks: this aims to clog up the pathways connecting your network. They make it difficult for genuine traffic (from customers or non-malicious visitors) to access the affected organization.
The scale of these attacks is measured in Gigabytes per second (Gbps). Assaults of several hundred Gbps have been reported, but anything above 20Gbps could knock out your network.
- Application Layer Attacks: In this case, the attacker sends requests that require considerable resources to handle. They cause the victim’s disk spaces and CPU to fill up with false logs.
What Motivates DDoS Attacks?
Here are the most common reasons why attackers launch DDoS assaults.
- Extortion: They may ask you for a ransom in exchange for ceasing their attacks.
- Cyber-Activism: Also known as ‘hacktivism’. Certain groups strike at organizations that they believe aren’t aligned with their cause (e.g. if they think the organization has a bad social or environmental record).
- Competition: A competitor may be responsible for a DDoS attack launched at your business.
- Lone Attackers: Some people may do this for other reasons, e.g. gaining the respect of a community of illegal hackers.
How Do You Protect Against DDoS Attacks?
You wouldn’t want to waste days recovering from a DDoS strike, or lose substantial amounts of money in that period. Here are some steps you can take to prevent this from happening:
- Design a Response Plan for DDoS Attacks
Document a response strategy for a DDoS attack. This should include ways to ensure business continuity even when a DDoS attack succeeds. Assign roles (for instance, a rapid response team) and establish communication systems that can be activated if this happens.
- Guard Against Other Threats to Your Networks
Many cyber attackers are now using DDoS as a diversionary tactic. They could keep IT teams engaged with a DDoS strike, while they launch malware at your systems. This calls for vigilance on your part. Don’t be so preoccupied with fending off a single threat that you forget to guard other posts.
- Track Your Traffic
Use monitoring tools to track traffic. Monitor for possible spikes in incoming network traffic, and keep an eye on suspicious IP addresses when you spot them. Note that sudden, sharp, and unexplained rises in traffic could be a sign that an attacker is ‘testing’ your defenses. If the threat isn’t checked at this early stage they may follow up with a major DDoS attack.
This measure isn’t enough to keep malicious agents away. But it does let you prepare for a possible strike against your network infrastructure.
- Set Up Network Security
You should have a combination of network security tools in place to protect against these strikes. These include firewalls, content filtering, anti-spam, and load balancing. Taken together, these should give you a moderate buffer against malicious traffic.
- Update Your Systems
Your old systems could have vulnerabilities in them that DDoS attackers could exploit. By updating your system, you gain access to the newest defenses that your IT service providers have to offer and stay a step ahead of the vandals.
- Work with an IT Security Solutions Provider
Unless you have a big, five-star in-house IT team, even your best efforts may fail to ward off a DDoS attack. That’s why you need to work with an IT security services company that takes on this task and delivers at the highest level.

The Nigerian Insurers Association has urged the House Committee on Capital Market and Institutions to respect the constitutional separation of powers as it carries out a probe on over 20 insurance firms.
In a statement on Tuesday night, the Director General/Chief Executive Officer of NIA, Mrs Bola Odukale, said the decision of NIA and the affected firms to approach the court was to seek clarity on the constitutional limits of the House Committee’s probe.
It would be recalled that the House of Representatives on Monday is investigating no fewer than 25 insurance companies operating in the country for various financial infractions spanning financial reporting, claims settlement, premium remittance, and issuance of policies.
The Chairman, House Sub-Committee on Capital Market and Institutions, Kwamoti Laori, during a meeting with the management of the insurance companies at the National Assembly Complex in Abuja, said the meeting was convened following the receipt of a petition on infractions by the insurance companies.
In the statement, Odukale said, “The Association wishes to state unequivocally that all actions taken by the NIA and the affected member companies in response to the Committee’s invitations and pronouncements were based entirely on legal advice by its Solicitors. It was on the firm instruction of legal counsel that recourse was made to the courts.
“The objective of approaching the Court is to seek judicial guidance on the legality, propriety, and constitutional limits of the Committee’s intervention in order to safeguard institutional integrity, uphold regulatory independence, and ensure that legislative oversight remains within the bounds of law.
“The Court action seeks to determine whether the current posture of the Committee reflects an exercise of legislative judgment, which, by constitutional design, is the exclusive province of statutory regulators, such as the National Insurance Commission, Securities and Exchange Commission, Nigerian Exchange, Financial Reporting Council, Nigeria Data Protection Commission, and the National Information Technology Development Agency.
“This raises serious questions about legislative overreach and an erosion of the doctrine of separation of powers, a cornerstone of Nigeria’s constitutional democracy.”
Odukale maintained that the NIA was committed to lawful and constructive engagement with all arms of government, provided that such engagement respects the autonomy of statutory regulators and the boundaries established by the Constitution.
“The NIA will continue to provide its full support to all member companies while upholding the principles of legal compliance and sector-wide integrity,” Odukale concluded.
17 of the companies that went to court were represented by their lawyer, Mr Abimbola Kayode, at the meeting with the committee.
Finance ministers and development partners from the Horn of Africa have called for enhanced digital integration to boost trade, drive economic growth and promote regional stability during the 25th Ministerial Meeting of the Horn of Africa Initiative (HoAI).
Held in Nairobi, on July 14, the meeting was co-chaired by the African Development Bank’s Vice President for Regional Development, Integration and Business Delivery, Nnenna Nwabufo and Somalia’s Minister of Finance, Bihi Iman Egeh. Discussions underscored the critical role of digital integration in reducing trade barriers, boosting government service delivery and creating employment — particularly for the region’s youth.
“Digital technologies are shaping today’s economy and tomorrow’s industries. By embedding these technologies into our programs, we can not only improve inclusion but also leapfrog outdated development models,” said Nwabufo.
She called for digital integration a “central enabler” in each of the Horn of Africa Initiative’s pillars – trade, infrastructure, resilience, and human capital,
Learning through experience
Drawing from global and regional success stories, speakers highlighted the transformative potential of technology-led development. The ministers pointed to the Philippines as a strong example, where ICT has generated millions of jobs in business process outsourcing. Similarly, Kenya’s fintech innovation—especially the success of M-PESA—was cited as a model for scaling digital financial services across the region.
Participants urged governments to proactively foster digital ecosystems by capitalizing on the demographic dividend, identifying infrastructure upgrades, tighter regulatory reforms, and digital skills trainings as priorities to enable broader participation in the digital economy.
Minister Egeh reiterated the need for more coordinated regional efforts to create the enabling environment required for accelerated digital integration and expansion. He referenced the HoAI Digital Policy Matrix, adopted in 2023 which provides a blueprint on how to address key obstacles to achieving effective digital integration across the region.
Barack Makokha, Kenya’s Cabinet Secretary for National Treasury, underscored the importance of regionally-aligned public private partnerships and advocated for blended financing to reduce investment risk and expand digital access in underserved areas.
World Bank Vice President for Eastern and Southern Africa, Ndiame Diop, called for a comprehensive multi-pronged approach, combining cross-border coordination, large-scale financing, robust policy support, and digital infrastructure investments. He pointed out that such measures could transform digital integration into, “a powerful engine of economic transformation” for the Horn of Africa—ensuring no one is left behind in the digital era.
The meeting concluded with a shared recognition that sustained political will and the determination to implement a multifaceted approach are essential to unlocking the region’s economic potential and driving long-term growth.
The event also welcomed observers from the East African Community, Agence française de développement, and Shelter Afrique, reflecting strong regional and international backing for the HoAI in the development community.
