Defending against Denial of Service (DoS) Attacks

What is a DoS Attack?

According to NIST, a denial of service (DoS) is:

“The prevention of authorized access to resources or the delaying of time-critical operations. (Time-critical may be milliseconds or it may be hours, depending upon the service provided).”

a distributed denial of service (DDoS) is:

“A denial of service technique that uses numerous hosts to perform the attack.”

Cloud Security – 26 Foundational Security Practises and Capabilities…

That is quite the catchy title don’t you agree? Ok so that needs some work and when we think about cloud security, we need to realise that Computing as a Service isn’t a silver bullet.

One Cloud to Rule them all and in the darkness bind them

Ok so the cloud was promised as the saviour of IT and Cyber security but the promise vs the reality. Well, let’s be frank, they don’t really match up. But have no fear – secure cloud design is here (omg cringe)! Ok now we have that out of my system let’s look at some basic cloud security considerations to make when thinking about cloud services.

Checklist

Ok so the world doesn’t work with a checklist however, if you are like me you will want to use lists and aides to jog the little grey cells into action. Let’s think about cloud services and security: Read more “Cloud Security – 26 Foundational Security Practises and Capabilities Checklist” →

Cyber Security Design Review

Purpose

To conduct a solution review we need to consider multiple perspectives. Cyber security can be described as (from the NCSC):

“Cyber security’s core function is to protect the devices we all use (smartphones, laptops, tablets and computers), and the services we access – both online and at work – from theft or damage. It’s also about preventing unauthorised access to the vast amounts of personal information we store on these devices, and online.”

Cyber Security is concerned with risks, threats, vulnerabilities, and controls. This really means the breadth and depth of cyber security is vastly wide and terribly deep. Read more “Cyber Security Design Review” →
