The metadata command does not have a lot of options to it, but you can narrow down the search to: In this case, I want to see all the hosts that have data in the ‘os’ index because I know data in that index will be of importance to me in my hunt. Maybe I want to isolatehosts that are writing to a specific index. Now that I know what types of data I have in Splunk, let's see which hosts are sending data through-do I have current data for all my hosts? Doing a little epoch time conversion, I determine that the data first hit my indexer on at 2:31:00 GMT and the last time it was seen on my indexer was 22:01:12 GMT.īased on the time range of my search - May 13 22:00 GMT to May 20 22:38:15 GMT - I have a high level of confidence that my FireEye data is fairly current, but if my investigation goes back before May 12, I don’t have FireEye data to work with, which could impact how I approach this activity or lower my confidence in determining when something was first seen in my network. This is a quick search that I could run to enumerate sourcetypes in Splunk for the past seven days.Īs you can see, in the past seven days I have 5,162 FireEye events. My first thought is to see that I have data sets available to me that pertain to the time I am hunting in. My manager has tasked me to start hunting based on some indicators recently gathered. These metadata fields (see what I did there?) can be searched and returned with values that include first time, last time and count for a particular value. host (hostname or IP that generated an event)._time, source (where the event originated could be a filepath or a protocol/port value).The metadata command is a generating command, which means it is the first command in a search.įor those not fully up to speed on Splunk, there are certain fields that are written at index time. We've updated it recently to maximize your value.) The metadata command for threat hunting (Part of our Threat Hunting with Splunk series, this article was originally written by Domenico “Mickey” Perre. Today, I am going to share with you my methodology around initial information gathering and how I use the metadata and tstats commands to understand the data available to me when I start threat hunting. Without this knowledge, you risk making assumptions that lead to poor decisions whilst threat hunting. To effectively hunt, understanding the data you have and don’t have for your hosts is key. Actually - in this case - know your network and hosts. What gaps might those be? As a wise man once said, Know thy network. What do I mean by that? Well, if you rush into threat hunting and start slinging SPL indiscriminately, you risk creating gaps in your investigation. As a Splunk Jedi once told me, you have to first go slow to go fast. So you want to hunt, eh? Well my young padwa…hold on. Using metadata and tstats to quickly establish situational awareness

There were various elements that came together to make Sitges a gay destination. ‘Why was he attracted to Sitges in 1914?’ he asks.Įven in the darkest days of Francoism, Sitges was a town that showed itself more tolerant than other Spanish towns, despite legislation defining prostitutes, vagabonds and homosexuals as criminals. An early foreign visitor was Sergei Diaghilev, the Russian ballet impresario and founder of the Ballets Russes, who came to Sitges in 1914 with his lover, the dancer Nijinsky. It was in Casablanca that other cultural initiatives were born, like the Irish-Catalan and Welsh-Catalan festivals, as well as Gay Sitges Link.’ Brandon Jones (left) and Juan Font, behind the bar at Casablanca.īrandon last year produced a documentary entitled ‘The Gay History of Sitges’ which aimed to show how a village that in 1900 had a population of 3,000 – now 30,000 – can embrace homosexuality, a subject that is still taboo in some countries and religions. Among our first customers were members of the Sitges Rugby Club (I am myself an ex rugby player) who mingled with younger lady members of the Sitges English Theatre Club which I co-founded 20 years ago. A lot of people think we are a gay bar but we are not, we are a heterosexual-friendly bar. The cultural aspect of it was very important. The European Court of Human Rights was set up.īrandon remembers: ‘We wanted to make Casablanca different from other bars, to have art exhibitions and local painters. Google was registered for the first time as a private company. That year, coincidentally, José María Aznar was in government and heading for a second term. ‘That was a glorious time for us and for Barcelona.’Ĭasablanca opened in 1998. I found the importer and I found Juan, the person I have shared the last 39 years of my life with.’Īn iconic year for Brandon and Joan was in 1992 with the Barcelona Olympics, during which time they worked as the representatives and the facilitators for the BBC. ‘That is how I met Juan in 1981 because I was in Barcelona and looking for an importer to Spain. The son of a coal miner, Brandon studied French at the University of Oxford supported by a grant, before going into the catering business and managing a number of bars and restaurants in London during the 1970s.īrandon then went into the whisky business and discovered Catalonia. He was born in 1951 in the Rhondda Valley, South Wales. He probably knows more people in the town than many of the local politicians.’ (TP)īrandon, according to another long-term Sitges resident and mutual friend, Dominic Begg, is a ‘cultural activist, extremely sociable and totally integrated in the local community. The former Casablanca cocktail bar in the picturesque Carrer de Pau Barrabeig of Sitges. ‘It’s a bit too early for cocktails,’ he tells me with a mischievous sense of humour and ‘ buen ambiente’ that has defined Casablanca since its inception, at least till Covid-19 limited its activities. But as its co-owner Brandon Jones explains as he approaches his 69th birthday, and his partner Juan Font his 65th, the couple thought it was time to retire while still retaining many years of fond memories.Īs the three of us sit down, at a safe distance, and during the bar’s daytime closure to the public, for our conversation in the intimate softly-lit interior of a bar that for over 21 years has drawn a loyal clientele from around the world, Brandon pours himself a glass of water. The legendary, much loved and unique cocktail bar finally closed its business on 23 October, thus marking the end of an era – for it has made a unique contribution to the cultural and social life of a town that boasts a history of innovation, creativity and civic tolerance.Ĭasablanca, like many other establishments, has suffered a dramatic drop in economic activity during the pandemic. A warm mid-morning, on the first Sunday in October in the Time of Covid and, surrounded by the bright whitewash and deep blue of the old quarter of Sitges, I walk down the steps of the picturesque Carrer de Pau Barrabeig to the discreet entrance at Number 5: ‘Casablanca’.

They, like the gigantic predinosaur griffinflies, lack the ability to fold their wings up against their bodies in the way modern insects do, although some evolved their own different way to do so. Modern dragonflies do retain some traits of their distant predecessors, and are in a group known as the Palaeoptera, ancient-winged. While both of those groups are sometimes referred to as "giant dragonflies", in fact true dragonflies/odonata are more modern insects that had not evolved yet.įurther information on the extinct genus of dragonfly: Libellulium The Protanisoptera, another ancestral group that lacks certain wing-vein characters found in modern Odonata, lived from the Early to Late Permian age until the end Permian event, and are known from fossil wings from current-day United States, Russia, and Australia, suggesting they might have been cosmopolitan in distribution. Known informally as "griffinflies", their fossil record ends with the Permian–Triassic extinction event (about 247 Mya). Museum of Toulouse Mesurupetala, Late Jurassic ( Tithonian), Solnhofen limestone, Germany Dragonflies in Oze National Parkĭragonflies and their relatives are similar in structure to an ancient group, the Meganisoptera, from the 325 Mya Upper Carboniferous of Europe, a group that included the largest insect that ever lived, Meganeuropsis permiana from the Early Permian, with a wingspan around 750 mm (30 in). Evolution The giant Upper Carboniferous dragonfly relative, Meganeura monyi, attained a wingspan around 680 mm (27 in). The infraorder Anisoptera comes from Greek ἄνισος anisos "unequal" and πτερόν pteron "wing" because dragonflies' hindwings are broader than their forewings. Their bright colours and agile flight are admired in the poetry of Lord Tennyson and the prose of H. They are symbols of courage, strength, and happiness in Japan, but seen as sinister in European folklore. They are used in traditional medicine in Japan and China, and caught for food in Indonesia. During mating, the male grasps the female at the back of the head, and the female curls her abdomen under her body to pick up sperm from the male's secondary genitalia at the front of his abdomen, forming the "heart" or "wheel" posture.įossils of very large dragonfly-like insects, sometimes called griffinflies, are found from 325 million years ago (Mya) in Upper Carboniferous rocks these had wingspans up to about 750 mm (30 in), though they were only distant relatives, not true dragonflies.ĭragonflies are represented in human culture on artefacts such as pottery, rock paintings, statues, and Art Nouveau jewellery. They have a uniquely complex mode of reproduction involving indirect insemination, delayed fertilization, and sperm competition. They are fast, agile fliers capable of highly accurate aerial ambush, sometimes migrating across oceans, and often live near water. In some species, the nymphal stage lasts up to five years, and the adult stage may be as long as 10 weeks, but most species have an adult lifespan in the order of five weeks or less, and some survive for only a few days. Dragonflies are agile fliers, while damselflies have a weaker, fluttery flight.ĭragonflies are predatory insects, both in their aquatic nymphal stage (also known as "naiads") and as adults. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each.ĭragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan, though usually lighter in build however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or above the abdomen. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. Adult dragonflies are characterized by a pair of large, multifaceted, compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Loss of wetland habitat threatens dragonfly populations around the world. Most are tropical, with fewer species in temperate regions. About 3,000 extant species of true dragonflies are known. A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. |
