Are Wireless Networks Vulnerable To The Same Types Of Denial-of-service Attacks As Wired Networks

Types of Wireless Attacks

WiFi Knowledge Resources — CWNA Official Report Guide 4th Ed.

WiFi networks can be vulnerable to a diverseness of different attacks. Because of this, it's of import to be aware of them then you can take the necessary steps to forbid and reduce their impact.

So this week we're going to look at what kind of attacks you should be aware of.

You can find out a lot more than in-depth data on these attacks in the CWNA Official Study Guide 4th Edition.

Rogue Wireless Devices:
A rogue wireless device, or admission point, is an unauthorised WiFi device added onto the network that isn't nether the management of the network admins. They allow potential attackers a gateway into the network.

This sort of device can be maliciously installed if the attacker has direct access to the wired network, only by and large they are added by staff that are non enlightened of the implications.

Peer-to-peer Attacks:
Devices that are connected to the same access points can be vulnerable to attacks from other devices connected to that admission point.

Most providers provide for an option such as "Client Isolation" which ensures that clients connected to the access point cannot communicate with eachother, preventing this issue.

Eavesdropping:
This is where wireless communications are monitored. In that location are ii types of of eavesdropping.

The start, casual eavesdropping, or sometimes called WLAN discovery, is where a wireless client actively scans for wireless admission points.

The 2d blazon, malicious eavesdropping, is the illegal kind. This is where someone tries to listen in on the information transferred between clients and the access point. Because of this, it is essential to encrypt your networks, as annihilation unencrypted can be listened in on.

Encryption Cracking:
This is where the attacker attempts to crack the encryption on the network. WEP networks are the nearly susceptible to this, existence that they tin exist hands cracked in as picayune as 5minutes.

It is important to ensure that you apply the about secure encryption you can, and avert using WEP where possible.

Authentication Attacks:
This is where the attacker scrapes a frame exchange between a client authenticating with the network, then they but run an offline lexicon attack.

With this sort of information, and depending on the forcefulness of the password, it could be just a affair of time before they crack the password and gain access. Considering of this it's of import to keep your login credentials equally secure as possible.

MAC Spoofing:
MAC spoofing is an extremely easy matter to do. Because of this, using MAC filtering to control which devices can connect to your network is not secure at all.

It can still be used in conjunction with other security measures to build upward an overall more than secure network architecture.

Management Interface Exploits:
This sort of attack can go an issue when you make use of some devices such every bit wireless controllers that let you to control your access points via things like web interfaces or console access.

Default login credentials are widely available on the net, so it's crucial to ensure that all devices are securely locked downward to prevent unauthorised access.

Wireless Hijacking:
This occurs in situations where the assailant configures their laptop to broadcast as a wireless access point, using the same SSID as a public hotspot.

They and so sit dorsum and unsuspecting victims cease up connecting to information technology, thinking information technology is the genuine public hotspot. This leaves them open up to peer-to-peer attacks as well equally monitor the victim's deportment on the network.

Denial of Service:
This term covers a number of dissimilar things. DoS attacks can occur on different layers.

Layer one attacks are known equally RF jamming attacks, and can be both intentional (aggressor generating a point to deliberately cause interference) and unintentional (devices such every bit microwaves or wireless phones causing interference.

Layer 2 attacks can occur in a number of different means. For example, an aggressor can flood an AP with spoofed association and disassociation requests.

At that place are solutions out at that place that are used to find these sort of attacks, and allow you to take steps in stopping them.

Social Engineering science:
Contrary to popular belief, most successful hacks are non achieved through scripts, software or tools. Most occur due to social engineering.

This is a technique used to manipulate people into giving out data, such as computer passwords, or information that will help attackers narrow downwards potential passwords. The best way to deal with this potential threat is to ensure that people are educated on security procedures such every bit irresolute passwords regularly, and not sharing individual information.
