The insecurity paradox
2011-08-29
The formula here attempts to explain a paradox in security analysis:
If it is true that security is only as strong as its weakest link, why are not those who use insecur...

An approach to an organization's risk factors (part 3)
In this third and final part of our article series about risk factors, we will examine Human attack factors and Physical factors.
An approach to an organization's risk factors (part 2)
The previous article discussed different procedures and systems that could be invoked in order to mitigate risk. In subsequent parts we will examine areas at risk, starting with Electronic factors.
An approach to an organization's risk factors (part 1)
The aim of this type of initial risk analysis is to identify potentially vulnerable points that may be exploited if they are not sufficiently secured.
Malicious images (codes)
The ease involved in creating QR codes that links to web pages implies that this will be a popular way to facilitate the propagation of malware for mobile devices.
Restricting access to net resources for "good reasons"
The target should be the illegal act itself, rather than the communication mediums that may be used in planning undesired activities.
Diversification of attack vectors
Computer systems are becoming increasingly sophisticated and complex with components that are individually computerized. This increases the attack surface for cybercriminals, and represents a challenge for users and the security industry.
Mobile (in)security
The steps that private users and organizations can take to protect themselves, are quite similar in character to protection of traditional computers.
Free music with an unwanted tune
Whenever malware authors find new vehicles to spread their malware, the probability for success increases immensely.
Digital Dumpster Diving
Dumpster diving is known as examining trash to find interesting items that have been discarded. This security article's title refers to examining digital trash, which for certain purposes may turn out to be useful.
Firesheep - an eye-opener or a tool for criminals
A little more than one week ago a new extension to the Firefox web browser was published. And it got attention for sure!
Man-in-the-middle goes Mobile
The term Man-in-the-middle in a security context refers to an attack where someone/-thing is inserted between two endpoints and intercepts the communication between those. The intent is usually to obtain information and use this for illegitimate purposes. Recently the term Man-in-the-mobile, abbreviated as Mitmo, emerged.
A plethora of malware for mobile phones to be expected soon (?)
In later years dangerous malicious software for mobile phones and other handheld devices has been predicted and expected by several analysts. Norman, however has traditionally been among those more reluctant in predicting that the explosion of if malicious software for mobile devices is imminent. In retrospective it seems safe to say that our view has proven correct (so far).
Those Lazy Hazy Crazy Days of Summer
Indeed, summer is associated with long, lazy, relaxing days in the sun. Nothing to worry about in the world. Unfortunately everyone does not take their vacation at the same time as you. Cyber crime does not stop during summer - in fact cyber criminals have their heyday during this season.
Upcoming? The age of the cyborgs
We should have been expecting it - some did. Late May this year a researcher in the U.K. claims to be the first person in the world infected by a computer virus.
Data harvesting by mistake
Using wireless networks for accessing the Internet has become increasingly popular. These days you can access the Internet from virtually anywhere by connecting to a wireless network.
Dangerous device diversification
Most organizations have been experiencing an explosion in the number and types of devices that are in use in their networks. Gone are the days when traditional desktop computers, servers and printers, hard-wired together, were the available hardware in the network.
New devices vulnerable for Internet based attacks, OR: The future is here
In our regular security articles, we have several times pointed out that security vulnerabilities and exploits are not restricted to "traditional" computers. We have predicted that several of the devices that our daily lives are filled with, may be exploited in the (near) future.
Hot stuff: Exploitable routers - a flash of the whole iceberg
A new type of malicious software has recently been getting some media attention. The most interesting part of this is the fact that the malware's targets are not traditional computers. Rather does this malware attack different types of devices, namely routers and modems.
Mobile phone threats - hype or (finally) truth?
So far there has been no really dangerous malicious software targeting mobile phones. The New Year 2009 started with a new, interesting threat to mobile phones, which may change this picture.
Los fantasmas del pasado resurgen con las memorias USB
El uso cada vez mayor de las memorias USB y su capacidad de almacenamiento constituyen un importante problema para la seguridad.
Puntos de acceso inalámbricos en lugares públicos: el mundo al alcance de su mano o una práctica de riesgo
Imagínese que una persona con malas intenciones se sienta en una cafetería para tomarse un capuchino y finge navegar por Internet, mientras que lo que realmente está haciendo es recopilar nombres de usuario y contraseñas de otros clientes del establecimiento.
Conectar dispositivos en todas partes: un reto para la seguridad
Es algo útil y eficaz, pero también una gran amenaza para la seguridad.
¡El gran hermano te ENCUENTRA!
El artículo de Norman "El gran hermano te ESCUCHA" " publicado el año pasado terminaba con la frase: Por ahora, la tecnología VoIP ofrece seguridad, pero... hay que tener cuidado porque nunca se sabe quién puede estar escuchando.
Sinners in the sun
Summer, sun and sweet sins are something that most people associate with happiness and innocent fun. But the thieves do not go on vacation! And there are plenty of sinners under the sun.
Wireless and portable security during the summer holiday
Holiday for you does not necessarily mean holiday for everybody. For hackers, virus authors and computer thieves the summer can be a golden opportunity if you do not have the proper protection. Many people are working wireless in the summertime, taking their laptops out in the open, enjoying the sun while working. Thoughts on safety, computer viruses and industrial espionage are not the first things that come to their minds.
La seguridad en las redes inalámbricas
Cada vez son más los usuarios particulares y las empresas que utilizan redes inalámbricas (WLAN). La mayoría de los usuarios conoce las ventajas que presentan las redes inalámbricas, pero no todo el mundo es consciente de los peligros que entraña su uso si no se toman las medidas de seguridad oportunas.
Proof of concept worm for handheld devices
The first worm that spreads through handheld devices, like mobile phones, is observed. This is a "proof of concept" program without malicious code.
