Enable do not Track in Mozilla Firefox

Firefox’s mobile version doesn’t offer the Do Not Track feature; you can only enable the feature in Firefox’s desktop version.

Start by launching Firefox on your computer. In the top-right corner, click the hamburger menu (three horizontal lines) and choose “Settings”.

From the left sidebar, select “Privacy & Security.” On the right pane, in the Website Privacy Preferences section, enable “Send Websites a Do Not Track Request”.

Cum utilizați comenzile rapide pentru linia de comandă Linux

Linia de comandă Linux vă oferă o cantitate extraordinară de putere. Obțineți acces de neegalat la funcționarea interioară a instalării dvs. Linux. Toate comenzile Linux, fișierele de configurare și alte instrumente vă stau la dispoziție. Dar caracteristica definitorie a liniei de comandă este și cel mai mare dezavantaj al acesteia: comenzile trebuie tastate.

Tastarea este relativ lentă. De asemenea, este ușor să faci greșeli de scriere, mai ales atunci când tastezi cuvinte neobișnuite, cum ar fi cifsiostat. Există un pericol legat de tastarea greșită a lucrurilor pe computere, iar Linux nu este diferit.

Dar, chiar dacă greșeala dvs. de scriere nu a provocat o pierdere de date sau un alt rezultat dramatic, repetiția și supărarea provocate de controlul computerului prin intermediul cuvântului tastat vă pot distruge entuziasmul pentru ceea ce încercați să faceți.

Protect your Network from CDP attacks

1. Disable CDP on Exposed Ports

It’s essential to use CDP only where it’s needed. Disable CDP on interfaces connected to untrusted networks or devices, such as guest networks or employee devices, to minimize the risk of sensitive network information being exposed.

  • Per interface: no cdp enable
  • Globally: no cdp run

2. Limit CDP Usage in Sensitive Areas

Enable CDP only where absolutely necessary, such as between core switches in the data center. Avoid enabling it on ports that connect the internal network to untrusted or external networks to prevent the exposure of sensitive details.

3. Implement Network Access Control (NAC)

Network Access Control (NAC) helps to authenticate and authorize devices connecting to the network, ensuring that only approved devices have access. This reduces the risk of unauthorized devices using CDP to gather information on the network’s structure.

4. Configure VLANs and Segment the Network

Segment your network using VLANs to limit interaction between different network segments. Separating production networks from employee or guest areas reduces CDP exposure to unauthorized devices and minimizes attack surfaces.

5. Monitor CDP Traffic for Suspicious Activity

Network traffic monitoring is essential for spotting suspicious activities. Use monitoring solutions to detect abnormal CDP messages or unknown devices sending such packets. Unusual CDP activity may indicate an intruder mapping out the network.

6. Consider LLDP if Working with Non-Cisco Equipment

If your network includes non-Cisco devices, consider using the Link Layer Discovery Protocol (LLDP), an open-standard protocol similar to CDP. LLDP allows for more granular control over shared information, reducing the risk of unnecessary data exposure.
