Stuxnet was also the first time a nation used a cyberweapon to attack another nation. [13] Following the Stuxnet attacks, Iran used cyberweapons to target top American financial institutions, including the New York Stock Exchange. [14] Stuxnet was subsequently followed by Duqu in 2011 and Flame in 2012. [11] Flame's complexity was unmatched at ...
Tamperproofing is a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system. Since any device or system can be foiled by a person with sufficient knowledge, equipment, and time, the term "tamperproof" is a misnomer unless some limitations on the tampering party's resources is explicit or assumed.
The device can then be unlocked with a password, biometric authentication, a physical dongle, a network interchange, a one-time password, or any combination thereof. If this device is a boot drive , however, it must be unencrypted in a pre-boot environment so the operating system can be accessed.
Physical access is a term in computer security that refers to the ability of people to physically gain access to a computer system. According to Gregory White, "Given physical access to an office, the knowledgeable attacker will quickly be able to find the information needed to gain access to the organization's computer systems and network." [1]
Tamper-evident physical devices are common in sensitive computer installations. For example, network cabling can be run down transparent conduits and switches can be located in glass-fronted cabinets, allowing for any unusual device attached to the network tending to stand out in plain view.
An attacker could, for example, use a social engineering attack and send a "lucky winner" a rogue Thunderbolt device. Upon connecting to a computer, the device, through its direct and unimpeded access to the physical address space, would be able to bypass almost all security measures of the OS and have the ability to read encryption keys, install malware, or control other system devices.
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
Particularly, an attacker can simply identify the data center of the Virtual Machine used by cloud computing, and retrieve information on the IP address and domain names of the data center. [23] It becomes dangerous when the attacker gains access to private cryptographic keys for specific servers which they may get data stored in the cloud. [ 23 ]
