Mário não consegue enviar um arquivo para o seu encarregado,
Jair. Após alguns testes, Marcos identificou que:
• As máquinas que estão conectadas no mesmo comutador já se comunicam entre si;
• A máquina do Mário está na Vlan 20, no switch Alfa e porta 8;
• A máquina do Jair se conecta através da porta 10, do switch Bravo e Vlan 20;
• Ambos os switches possuem máquinas na Vlan 20 e Vlan200; e
• A porta para interligação entre os switches é a porta 24 de cada equipamento.

Renata presta serviço para a área de redes para a empresa B.
Renata identificou que muitos usuários ainda faziam uso do
telnet para efetuar login remoto e iniciou a implementação do
SSH. Este garante segurança no login remoto, além de oferecer
uma capacidade cliente/servidor mais genérica, e pode ser usado
para funções de rede como transferência de arquivos e e-mail.
Para a implementação correta, o SSH faz uso de vários
protocolos.

Segurança da Informação
O Ataque “Ping da morte" é um ataque de negação de serviço
(DoS) em que o invasor visa interromper uma máquina alvo
enviando um pacote maior que o tamanho máximo permitido,
fazendo com que a máquina visada trave ou falhe. De forma a
evitar esse ataque, o Departamento de Segurança do Tribunal de
Contas do Estado de São Paulo (TCE SP) resolveu bloquear as
requisições de PING, impedindo que outro computador utilize
esse comando para obter informações sobre o servidor.
Para isso, efetuará o bloqueio com o Iptables.
Sabendo-se que a interface do servidor é eth0, o comando de aplicação da regra de bloqueio no IPTABLES é:

SP) identificou um ataque por vírus e que este estava ocorrendo e
efetuando o apagamento de arquivos no servidor. Em virtude da
forma de backup utilizada, notou-se também que os mesmos
arquivos também eram apagados no backup. Logo, o TCE SP
decidiu trocar o tipo de backup usado pelo backup em nuvem. O
tipo de backup executado pelo TCE SP, antes da implementação
do backup em nuvem, é o backup:

Is It Live, or Is It Deepfake?
It’s been four decades since society was in awe of the quality of
recordings available from a cassette recorder tape. Today we
have something new to be in awe of: deepfakes. Deepfakes
include hyperrealistic videos that use artificial intelligence (AI) to
create fake digital content that looks and sounds real. The word is
a portmanteau of “deep learning” and “fake.” Deepfakes are
everywhere: from TV news to advertising, from national election
campaigns to wars between states, and from cybercriminals’
phishing campaigns to insurance claims that fraudsters file. And
deepfakes come in all shapes and sizes — videos, pictures, audio,
text, and any other digital material that can be manipulated with
AI. One estimate suggests that deepfake content online is
growing at the rate of 400% annually.
There appear to be legitimate uses of deepfakes, such as in the
medical industry to improve the diagnostic accuracy of AI
algorithms in identifying periodontal disease or to help medical
professionals create artificial patients (from real patient data) to
safely test new diagnoses and treatments or help physicians
make medical decisions. Deepfakes are also used to entertain, as
seen recently on America’s Got Talent, and there may be future
uses where deepfake could help teachers address the personal
needs and preferences of specific students.
Unfortunately, there is also the obvious downside, where the
most visible examples represent malicious and illegitimate uses.
Examples already exist.
Deepfakes also involve voice phishing, also known as vishing,
which has been among the most common techniques for
cybercriminals. This technique involves using cloned voices over
the phone to exploit the victim’s professional or personal
relationships by impersonating trusted individuals. In March
2019, cybercriminals were able to use a deepfake to fool the CEO
of a U.K.-based energy firm into making a US$234,000 wire
transfer. The British CEO who was victimized thought that the
person speaking on the phone was the chief executive of the
firm’s German parent company. The deepfake caller asked him to
transfer the funds to a Hungarian supplier within an hour,
emphasizing that the matter was extremely urgent. The
fraudsters used AI-based software to successfully imitate the
German executive’s voice. […]
What can be done to combat deepfakes? Could we create
deepfake detectors? Or create laws or a code of conduct that
probably would be ignored?
There are tools that can analyze the blood flow in a subject’s face
and then compare it to human blood flow activity to detect a
fake. Also, the European Union is working on addressing
manipulative behaviors.
There are downsides to both categories of solutions, but clearly
something needs to be done to build trust in this emerging and
disruptive technology. The problem isn’t going away. It is only
increasing.
