When I was growing up, security meant soldiers at a border, police on the streets, or customs officers checking goods at an entry point. Today, those images tell only part of the story. Today, borders have become porous in ways our grandparents could never have imagined. The enemy no longer has to cross a fence or sail into our ports. They can sit behind a computer screen, thousands of miles away, and still cripple a hospital, shut down a bank, or manipulate an election.
This is why I call cyberspace the new frontline of security. It is both national and personal. It is as much about government strategy as it is about your own daily habits — the password you choose, the links you click, the files you open. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) says it plainly: every sector — hospitals, banks, schools, water plants, energy grids, even individuals at home — is now a potential target. And in Kenya, we are no different. If anything, our growing dependence on mobile money, online banking, and cloud-based services makes us equally vulnerable.
The danger in the cyber domain is that it never stands still. Defenses that worked yesterday may be useless today. Hackers innovate constantly — using artificial intelligence to write phishing emails that read like they were crafted by your closest friend, exploiting software flaws the moment they are discovered, and hiding their money trails in cryptocurrency wallets. The battlefield may be invisible, but the damage is painfully real: stolen savings, collapsed business systems, blacked-out nations.
Cyber threats come in many forms, some as familiar as email scams, others as sophisticated as nation-state sabotage. Ransomware has become a favorite weapon. In 2024, a coordinated attack on hospital networks in Illinois, Indiana, and Ohio forced patient transfers and delayed critical surgeries. I have seen similar risks here in Africa, where hospitals rely on outdated systems and a ransomware hit could be devastating.
Phishing and spear-phishing are even more common. These are deceptive messages designed to trick you into revealing your passwords or installing malware. The frightening part is how convincing they’ve become — AI can now create perfectly worded, personalized messages that are almost impossible to spot.
Distributed Denial of Service (DDoS) attacks overwhelm systems with traffic until they crash. In 2023, one took down a U.S. state’s unemployment benefits portal, leaving thousands without access to much-needed funds. Imagine if a similar attack targeted Kenya’s eCitizen platform — the disruption would be massive.
Supply chain compromises are another growing risk. The infamous SolarWinds breach showed how hackers could attack one trusted software supplier and, in doing so, infiltrate thousands of government and corporate systems.
And then there are critical infrastructure attacks — cyber operations targeting power plants, water treatment facilities, or transport networks. In 2023, Iranian-linked hackers breached a U.S. municipal water plant and briefly altered chemical levels in the supply. If such an attack were aimed at Nairobi’s water system, the consequences could be catastrophic.
Some of the most skilled and dangerous players in this space are nation-states themselves. Russia, China, Iran, and North Korea all maintain cyber units capable of stealing secrets, sabotaging systems, and spreading disinformation.
Russia has used cyberattacks alongside missiles in Ukraine, striking power grids to leave civilians in darkness during winter. China continues to target defense contractors, stealing blueprints for advanced weapons. Iran has gone after critical infrastructure — including the water plant incident in the U.S. — while North Korea treats cybercrime as a source of hard currency, stealing billions in cryptocurrency.
For a Kenyan citizen, these events may seem distant. But remember: in a connected world, a cyberattack in Europe or the U.S. can ripple into Africa in hours. Our financial systems, mobile money platforms, and even critical imports rely on digital networks that are all linked globally. Cybersecurity professionals often say, “Humans are the weakest link.” And they’re right — but I believe humans can also be the strongest defense.
Many cyberattacks begin with social engineering — tricking a person into giving away access. A U.S. city lost over $800,000 when an employee wired money to a “vendor” after receiving a spoofed email that looked like it came from the city’s finance director. No hacking tools needed — just human trust exploited.
On the other hand, a sharp-eyed citizen can stop an attack before it causes damage. In 2024, a university student in Arizona noticed a suspicious login to his account from Eastern Europe and reported it. IT staff discovered a larger intrusion targeting sensitive defense research. That one alert made the difference. In Kenya, I’ve seen similar moments — like when a bank account holder spotted a suspicious funds transfer request and froze it.
Our most essential systems — power, water, transport, healthcare, finance — are prime cyber targets. In 2021, the Colonial Pipeline ransomware attack disrupted fuel supplies across the Eastern U.S. for days. In 2024, a cyberattack on a Midwest energy utility left 300,000 residents facing rolling blackouts in extreme heat.
Kenya’s own critical infrastructure is not immune. An attack on our power grid, mobile money systems, or major banks could paralyze daily life. Protecting these assets requires government–private sector cooperation — and citizen awareness. Even something as simple as reporting unusual water discoloration or unexplained transport disruptions can alert authorities to a possible cyber-linked sabotage.
We are entering a new phase where cyber threats will be supercharged by emerging technologies. Artificial intelligence is already being misused to create deepfake videos, clone voices, and run phishing operations at scale. In 2024, criminals in the U.S. used an AI-generated voice clone of a company CEO to trick an employee into wiring $25 million.
Cybersecurity is now a core part of national defense in all countries. Agencies like CISA, the FBI’s Cyber Division, and U.S. Cyber Command lead the fight in America. In Kenya, our Communication Authority, Directorate of Criminal Investigations (DCI), and National KE-CIRT (Kenya Computer Incident Response Team Coordination Centre) work to detect and respond to cyber incidents. But governments can’t do it alone. Cybersecurity is now a subject of international diplomacy — countries are negotiating norms for responsible behavior online. Yet enforcing these norms is difficult because cyberattacks can be masked or routed through other nations.
And this is where you and I come in. As citizens, we can raise our own defenses: use strong, unique passwords, enable multi-factor authentication, keep devices and software updated and treat unsolicited requests for information with suspicion.
In this connected age, cybersecurity is everyone’s fight. The line between national defense and personal responsibility has blurred. Your careless click can bring down a corporate network; a corporate breach can expose your family’s private data.
The health of a nation’s digital infrastructure depends on what happens at the grassroots just as much as on what happens in intelligence headquarters. The cyber world has no borders, and in this fight, every citizen is a frontline defender.
