  • Driftnet command tutorial and examples

    Sniffing consists of intercepting packets through a network to get their content. When we share a network, intercepting the traffic going through it is pretty easy with a sniffer, that’s why protocol encryption such as https is so important, when traffic is unencrypted even credentials go in plain text and can be intercepted by attackers.

    The specific Cisco switch I configured was a Catalyst 3560 series PoE-48. I am sure these direction will work with other similar devices. Since I am an openSUSE user, the directions are tailored as such.

  • Insights into hybrid cloud: Here's what to consider

    Our interactions with businesses can happen in person, on the web, on our mobile devices, in marketplaces or via APIs. To enable these interactions, IT organizations are increasingly being driven towards hybrid IT architectures involving private cloud, public cloud, edge computing, AI/ML and more to provide multiple different routes to the customer.

Research shows that improving business agility and increasing IT agility are key drivers for organizations that are implementing a hybrid cloud strategy.
